powerpc/32s: Fix cleanup_cpu_mmu_context() compile bug
Currently pmac32_defconfig with SMP=y doesn't build:
arch/powerpc/platforms/powermac/smp.c:
error: implicit declaration of function 'cleanup_cpu_mmu_context'
It would be nice for consistency if all platforms clear mm_cpumask and
flush TLBs on unplug, but the TLB invalidation bug described in commit
01b0f0eae081 ("powerpc/64s: Trim offlined CPUs from mm_cpumasks") only
applies to 64s and for now we only have the TLB flush code for that
platform.
So just add an empty version for 32-bit Book3S.
Fixes: 01b0f0eae081 ("powerpc/64s: Trim offlined CPUs from mm_cpumasks")
