powerpc: Revert CHRP boot wrapper to real-base = 12MB on 32-bit
Commit 9b09c6d909dfd8de96b99b9b9c808b94b0a71614 ("powerpc: Change the
default link address for pSeries zImage kernels") changed the
real-base value in the CHRP note added by addnote to the zImage from
12MB to 32MB. It turns out that this causes unnecessary extra reboots
on old 32-bit CHRP machines. This therefore adds a -r flag to addnote
to allow us to specify what real-base value it should put in the CHRP
note, and adjusts the wrapper script to pass -r c00000 to addnote when
making a zImage for a CHRP machine. Also, CHRP machines ignore the
RPA note, so we don't need to arrange for it to be the same as the
kernel's.
