x86/asm: Add pud/pmd mask interfaces to handle large PAT bit

The PAT bit gets relocated to bit 12 when PUD and PMD mappings are
used.  This bit 12, however, is not covered by PTE_FLAGS_MASK, which
is used for masking pfn and flags for all levels.

Add pud/pmd mask interfaces to handle pfn and flags properly by using
P?D_PAGE_MASK when PUD/PMD mappings are used, i.e. PSE bit is set.
