Christophe Leroy feb8e960d7 powerpc/mm: Fix CONFIG_PPC_KUAP_DEBUG on PPC32 ...

CONFIG_PPC_KUAP_DEBUG is not selectable because it depends on PPC_32
which doesn't exists.

Fixing it leads to a deadlock due to a vital register getting
clobbered in _switch().

Change dependency to PPC32 and use r0 instead of r4 in _switch()
