Revert "powerpc: Sync RPA note in zImage with kernel's RPA note"

This reverts commit 91a00302959545a9ae423e99732b1e46eb19e877, plus
commit 0dcd440120ef12879ff34fc78d7e4abf171c79e4 ("powerpc: Revert CHRP
boot wrapper to real-base = 12MB on 32-bit") which depended on it.

Commit 91a00302 was causing NVRAM corruption on some pSeries machines,
for as-yet unknown reasons, so this reverts it until the cause is
identified.
