Rather than accessing the attributes of TYPE_CCSR directly, use the SysBusDevice
API which exists exactly for that purpose. Furthermore, registering the memory
region with the SysBusDevice API makes it show up in QMP's `info qom-tree`
command.

This reverts commit d0b25425749d5525b2ba6d9d966d8800a5643b35.
Loading firmware from the PCI host is unusual and raven is only used
by one board so this does not simplify anything but rather complicates
it. Revert to loading firmware from board code as that is the usual
way and also because raven has nothing to do with ROM so it is not a
good place for this.

The GT-64120 PCI controller requires special handling where:
1. Host bridge(bus 0 ,device 0) must never be byte-swapped
2. Other devices follow MByteSwap bit in GT_PCI0_CMD
The previous implementation incorrectly swapped all accesses, breaking
host bridge detection (lspci -d 11ab:4620).
Changes made:
1. Removed gt64120_update_pci_cfgdata_mapping() and moved data_mem initialization
to gt64120_realize() for cleaner setup
2. Implemented custom read/write handlers that:
- Preserve host bridge accesses (extract32(config_reg,11,13)==0)
- apply swapping only for non-bridge devices in big-endian mode

Each non-core chiplet on a chip has a "pervasive chiplet" unit and its
xscom register set. This adds support for PHB4/5.
skiboot reads the CPLT_CONF1 register in __phb4/5_get_max_link_width(),
which shows up as unimplemented xscom reads. Set a value in PCI CONF1
register's link-width field to demonstrate skiboot doing something
interesting with it.
In the bigger picture, it might be better to model the pervasive
chiplet type as parent that each non-core chiplet model derives from.
For now this is enough to get the PHB registers implemented and working
for skiboot, and provides a second example (after the N1 chiplet) that
will help if the design is reworked as such.

On the real device, the PCIe root bus is only connected to a PCIe bridge and
does not allow for direct attachment of devices. Doing so in QEMU results in no
PCI devices being detected by Linux. Instead, PCI devices should plug into the
secondary PCIe bus spawned by the internal PCIe bridge.
Unfortunately, QEMU defaults to plugging devices into the PCIe root bus. To work
around this, every PCI device created on the command line needs an extra
`bus=dw-pcie` option which is error prone. Fix that by marking the PCIe root bus
as full which makes QEMU decend into the child PCIe bus.

Each Astro on 64-bit machines supports up to four LMMIO regions.
Those regions are used by graphic cards and other PCI devices which
need to map huge memory areas. The LMMIO regions are configured and
set up by SeaBIOS-hppa and then used as-is by the operating systems
(Linux, HP-UX).
With this addition it's now possible to add other PCI graphic
cards on the command line, e.g. with "-device ati-vga".

Some boards such as vmapple don't do real legacy PCI IRQ swizzling.
Instead, they just keep allocating more board IRQ lines for each new
legacy IRQ. Let's support that mode by giving instantiators a new
"nr_irqs" property they can use to support more than 4 legacy IRQ lines.
In this mode, GPEX will export more IRQ lines, one for each device.

The MV64361 has two PCI buses one of which is used for AGP on
PegasosII. So far we only emulated the PCI bus on pci.1 but some
graphics cards are only recognised by some guests when connected to
pci.0 corresponding to the AGP port. So far the interrupts were not
routed from pci.0 so this patch fixes that allowing the use of both
PCI buses. On real board only INTA and INTB are connected for AGP but
to avoid surprises we connect all 4 PCI interrupt lines so pci.0 can
be used for all PCI cards as well.

Use of assert(false) can trip spurious control flow warnings from
some versions of GCC (i.e. using -fsanitize=thread with gcc-12):
error: control reaches end of non-void function [-Werror=return-type]
default:
g_assert_not_reached();
break;
| ^^^^^
Solve that by removing the unreachable 'break' statement, unifying
the code base on g_assert_not_reached() instead.

When multiple QOM types are registered in the same file,
it is simpler to use the the DEFINE_TYPES() macro. In
particular because type array declared with such macro
are easier to review.

Reset config values in the device RESET phase, not only once
when the device is realized, because otherwise the device can
use unknown values at reset.
Since we are adding a new reset method, use the preferred
Resettable API (for a simple leaf device reset, a
DeviceClass::reset method and a ResettableClass::reset_hold
method are essentially identical).

Since this device is only used by MIPS machines which aren't
versioned, we don't need to update migration compat machinery.
Mention the datasheet referenced. Remove the "Malta assumptions
ahead" comment since the reset values from the datasheet are used.

Currently, PCI link devices (PNP0C0F) are always created within the
scope of the PCI root bridge. However, RISC-V needs these link devices
to be created outside to ensure the probing order in the OS. This
matches the example given in the ACPI specification [1] as well. Hence,
create these link devices directly under _SB instead of under the PCI
root bridge.
To keep these link device names unique for multiple PCI bridges, change
the device name from GSIx to LXXY format where XX is the PCI bus number
and Y is the INTx.
GPEX is currently used by riscv, aarch64/virt and x86/microvm machines.
So, this change will alter the DSDT for those systems.

We pass a ResetType argument to the Resettable class enter
phase method, but we don't pass it to hold and exit, even though
the callsites have it readily available. This means that if
a device cared about the ResetType it would need to record it
in the enter phase method to use later on. Pass the type to
all three of the phase methods to avoid having to do that.
