Subject: [PATCH v2 2/2] powerpc: rectify selection to ARCH_ENABLE_SPLIT_PMD_PTLOCK

Commit 66f24fa766e3 ("mm: drop redundant ARCH_ENABLE_SPLIT_PMD_PTLOCK")
selects the non-existing config ARCH_ENABLE_PMD_SPLIT_PTLOCK in
./arch/powerpc/platforms/Kconfig.cputype, but clearly it intends to select
ARCH_ENABLE_SPLIT_PMD_PTLOCK here (notice the word swapping!), as this
commit does select that for all other architectures.

Rectify selection to ARCH_ENABLE_SPLIT_PMD_PTLOCK instead.

Fixes: 66f24fa766e3 ("mm: drop redundant ARCH_ENABLE_SPLIT_PMD_PTLOCK")
