powerpc/32: Allow fragmented physical memory

Since commit 9e849f231c3c ("powerpc/mm/32s: use generic mmu_mapin_ram()
for all blocks.") it is possible to map all blocks as RAM on any PPC32.

Remove related restrictions.

And remove call to wii_memory_fixups() which doesn't do anything else
than checks since commit 160985f3025b ("powerpc/wii: remove
wii_mmu_mapin_mem2()")
