There are no more users left for any pxd_ERROR() either in generic MM or
in the platform MM. Hence all these platform macros along with their
generic fallback could be dropped across the tree.

Move the pfn_pte() definitions from the 2level and 4level files to the
generic pgtable.h and delete the custom definition of mk_pte() so that we
use the central definition.

The _PAGE_NEWPAGE bit does not really indicate that this is a new page,
but rather whether this entry needs to be synced or not. Renaming it
to _PAGE_NEEDSYNC will make it more clear how everything ties together.

available.
