x86/mm: Add prot_sethuge() helper to abstract out _PAGE_PSE handling
We still have some historic cases of direct fiddling of page
attributes with (dangerous & fragile) type casting and address shifting.
Add the prot_sethuge() helper instead that gets the types right and
doesn't have to transform addresses.
( Also add a debug check to make sure this doesn't get applied
to _PAGE_BIT_PAT/_PAGE_BIT_PAT_LARGE pages. )
