arm64/mm: Rename pte_mkpresent() as pte_mkvalid()

pte_present() is no longer synonymous with pte_valid() as it also tests for
pte_present_invalid() as well. Hence pte_mkpresent() is misleading, because
all that does is make an entry mapped, via setting PTE_VALID. Hence rename
the helper as pte_mkvalid() which reflects its functionality appropriately.
