[PATCH 1/3] mm: Move lowmem_page_address() a little later

[Huacai Chen <chenhuacai@loongson.cn>]

LoongArch will override page_to_virt() which use page_address() in the
KFENCE case (by defining WANT_PAGE_VIRTUAL/HASHED_PAGE_VIRTUAL). So move
lowmem_page_address() a little later to avoid such build errors:

error: implicit declaration of function 'page_address'.
