when a ifdef is used in the below manner, second one could be considered as
duplicate.
ifdef DEFINE_A
...code block...
ifdef DEFINE_A
...code block...
endif
...code block...

few places in arch/powerpc where this pattern was seen. In addition to that
in paca.h, CONFIG_PPC_BOOK3S_64 was defined back to back. merged the two
ifdefs.
No functional change is intended here. It only aims to improve code
readability.
