arm64: mm: fold init_pgd() into __create_pgd_mapping()
The routine __create_pgd_mapping() does nothing except calling init_pgd(), which has no other callers. So fold the latter into the former. Also, drop a comment that has gone stale. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
