mm: mmu_gather: prepare to gather encoded page pointers with flags
This is purely a preparatory patch that makes all the data structures
ready for encoding flags with the mmu_gather page pointers.
The code currently always sets the flag to zero and doesn't use it yet,
but now it's tracking the type state along. The next step will be to
actually start using it.
