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.

When doing error injection to 32-bits MMIO range, fixed length 8MB
is used. That's incorrect as one PE might span multile segments.
Also the 32-bits MMIO segment size isn't 8MB necessarily.
The patch fixes the issue to cover all (contiguous) 32-bits MMIO
segments assigned to the specified PE. Also, it fixes the 48 bits
of 50 bits AIB address, instead of all bits used for comparison.

The patch implements phb3 backend to support error injection. For 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 M32DT or RTT_TABLE.
As IO space isn't supported on PHB3, we're not going to support IO error
injection on PHB3.
All PEs have same DMA space. So we can't distinguish individual PE's
space and don't support DMA error injection for now. Perhaps we don't
understand how to do that. It needs more time for more investigation.
64-bits error injection will be supported later.
