powerpc: pmd_move_must_withdraw() is only needed for CONFIG_TRANSPARENT_HUGEPAGE
The linux-next build of powerpc64 allnoconfig fails with:
arch/powerpc/mm/book3s64/pgtable.c:557:5: error: no previous prototype for 'pmd_move_must_withdraw'
557 | int pmd_move_must_withdraw(struct spinlock *new_pmd_ptl,
| ^~~~~~~~~~~~~~~~~~~~~~
Caused by commit:
c6345dfa6e3e ("Makefile.extrawarn: turn on missing-prototypes globally")
Fix it by moving the function definition under
CONFIG_TRANSPARENT_HUGEPAGE like the prototype. The function is only
called when CONFIG_TRANSPARENT_HUGEPAGE=y.
