powerpc: Remove STRICT_KERNEL_RWX incompatibility with RELOCATABLE
[ Upstream commit c55d7b5e64265fdca45c85b639013e770bde2d0e ]
I have tested this with the Radix MMU and everything seems to work, and
the previous patch for Hash seems to fix everything too.
STRICT_KERNEL_RWX should still be disabled by default for now.
Please test STRICT_KERNEL_RWX + RELOCATABLE!
