arm64/mm: Clear PXX_TYPE_MASK and set PXD_TYPE_SECT in [pmd|pud]_mkhuge()

Browse source

Clear PXX_TYPE_MASK in [pmd|pud]_mkhuge() while creating section mappings
instead of just the PXX_TABLE_BIT and also set PXD_TYPE_SECT. Also ensure
PTE_VALID does not get modified in these helpers, because present-invalid
entries should preserve their state across.
