It's been a good long while since either OPAL POWER7 user touched a
machine, and even longer since they'd have been okay using an old
version rather than tracking master.
There's also been no testing of OPAL on POWER7 systems for an awfully
long time, so it's pretty safe to assume that it's very much bitrotted.
It also saves a whole 14kb of xz compressed payload space.

In several places, a "bus/device/function" u16 was being directly
or'ed into an address using a left-shift. This should be using
SETFIELD, especially now that all _LSH have been removed.
Change use of BDFN (bus/device/function) field from using plain
left-shift to using SETFIELD(). Add proper BDFN field definitions.

The last patch changed the SETFIELD() and GETFIELD() macros to automatically
calculate the shift of a given mask, so manually specifying the shift is no
longer needed. Additionally, any masks should have the _MASK suffix removed
since the GETFIELD() and SETFIELD() operations expected to be passed the
mask name without the _MASK suffix (and so either the mask name or the
get/setfield call needs to have its mask name changed).
Change all _MASK masks to remove the _MASK suffix, except for any places
that leaving _MASK makes sense (e.g. already an existing define without
_MASK suffix).
Remove all _LSH defines, as they are no longer needed.

The patch implements P7IOC backend to support error injection. There are
3 registers (control, address and mask) for each P7IOC PHB to do error
injection. The way to do error injection is straight-forward. For IO,
MMIO and PCI-CFG error injection, we check the address is valid or not.
The address will be used for error injection if that's valid. Otherwise,
we have to figure one out from IODT, M32DT or PELTM.
As DMA address is natually invisible to users, we just figure it out from
TVT and use that for error injection.
64-bits error injection will be supported later.
