We are preparing to add sparse vmemmap support to LoongArch. MIPS and
LoongArch need to call pgd_init()/pud_init()/pmd_init() when populating
page tables, so adjust their prototypes to make generic helpers can call
them.
NIOS2 declares pmd_init() but doesn't use, just remove it to avoid build
errors.

Pre-existing, but why not use:
pgd_init(&swapper_pg_dir[USER_PTRS_PER_PGD]);
?
Otherwise:
