Subject[PATCH] powerpc: fix up PPC_FSL_BOOK3E build
Commit

1c9df907da83 ("random: fix circular include dependency on arm64 after addition of percpu.h")

exposed a curcular include dependency:

asm/mmu.h includes asm/percpu.h, which includes asm/paca.h, which
includes asm/mmu.h

So fix it by extracting the small part of asm/mmu.h that needs
asm/percu.h into a new file and including that where necessary.

I have done powerpc test builds of allmodconfig, ppc64e_defconfig and
corenet64_smp_defconfig.
