[PATCH] powerpc: add more asm-prototypes.h declarations for asm exports

[Nicholas Piggin]

After patch 4efca4ed0 ("kbuild: modversions for EXPORT_SYMBOL() for asm"),
asm exports can get modversions CRCs generated if they have C definitions
in asm-prototypes.h. This patch adds missing definitions for 32 and 64 bit
allmodconfig builds.

Fixes: 9445aa1a3062 ("ppc: move exports to definitions")

Hi,

This should go into 4.9 to correct the modversions regression. Sorry it's
taken this long, the kbuild side took a while.

Thanks,
Nick
