powerpc/mm/book3s64: Move kfence and debug_pagealloc related calls to __init section

Move a few kfence and debug_pagealloc related functions in hash_utils.c
and radix_pgtable.c to __init sections since these are only invoked once
by an __init function during system initialization.

i.e.
- hash_debug_pagealloc_alloc_slots()
- hash_kfence_alloc_pool()
- hash_kfence_map_pool()
  The above 3 functions only gets called by __init htab_initialize().

- alloc_kfence_pool()
- map_kfence_pool()
  The above 2 functions only gets called by __init radix_init_pgtable()

This should also help fix warning msgs like:

>> WARNING: modpost: vmlinux: section mismatch in reference:
hash_debug_pagealloc_alloc_slots+0xb0 (section: .text) ->
memblock_alloc_try_nid (section: .init.text)
