Drop legacy data for dra7 and omap4/5 for genpd support for v5.13

Similar to what we have already done for am3 and 4, we can now boot dra7,
omap4, and omap5 with devicetree data and genpd without legacy SoC specific
built-in data.

Let's drop the legacy data for these SoCs, and the related "ti,hwmods"
custom devicetree property. As with these changes we now expect to have
complete devicetree data, let's also warn in the case if an old devicetree
data is noticed. And with the warning provided, there should not be any
need to delay dropping the legacy data as it just unnecessarily complicates
things.

The main reasons for dropping the legacy data is to avoid the burden of
maintaining a mixed boot process where both legacy built-in data and
devicetree data are needed. And we can now use standard reset driver,
genpd, and simple-pm-bus features.

These patches are based on the related devicetree changes to add the
missing interconnect target module configuration for these SoCs.

With the recent changes we are now booting am3/4, dra7, and omap4/5

Merge together branches dropping legacy data to avoid a minor merge conflict.

Merge together genpd related dts changes to provide base for dropping the

In preparation for probing l3 with simple-pm-bus and genpd, we must move
l3 noc to a separate node. This is to prevent omap_l3_noc.c driver from

We need mmio-sram early for omap4_sram_init() for IO barrier init, and
will be moving l3 interconnect to probe with simple-pm-bus that probes
at module_init() time. So let's move mmio-sram out of l3 to prepare for
that.

Otherwise we will get the following after probing the interconnects with
simple-pm-bus:

We can now probe devices with device tree only configuration using
ti-sysc interconnect target module driver. Let's configure the
module, but keep the legacy "ti,hwmods" peroperty to avoid new boot
time warnings. The legacy property will be removed in later patches
together with the legacy platform data.

Note that the old sysc register offset is wrong, the real offset is at
0x1100 as listed in TRM for SATA_SYSCONFIG register. Looks like we've been
happily using sata on the bootloader configured sysconfig register and
nobody noticed. Also the old register range for SATAMAC_wrapper registers
is wrong at 7 while it should be 8. But that too seems harmless.

There is also an L3 parent interconnect range that we don't seem to be
using. That can be added as needed later on.
