powerpc: fix up for mmu_mapin_ram api change

Today's linux-next build (powerpc ppc44x_defconfig) failed like this:

arch/powerpc/mm/pgtable_32.c: In function 'mapin_ram':
arch/powerpc/mm/pgtable_32.c:318: error: too many arguments to function 'mmu_mapin_ram'

Casued by commit de32400dd26e743c5d500aa42d8d6818b79edb73 ("wii: use both
mem1 and mem2 as ram").
