PM: Modified FFDC to avoid corruption of RC in error path.

On FSP platform, in case of some errors, HWP captures
certain EX level registers. To ensure availability of
such registers, FSP first attempts special wakeup.
Special wakeup HWP uses FAPI_TRY in its code path. It
is known that in FFDC collection path, use of FAPI_TRY
leads to corruption of original FAPI2 RC. Commit
removes such registers from the capture list.
