As a preparatory step to allow us to allocate early page tables from unmapped memory using memblock_alloc, modify the __create_mapping callees to map and unmap the tables they modify using fixmap entries.
All but the top-level pgd initialisation is performed via the fixmap. Subsequent patches will inject the pgd physical address, and migrate to using the FIX_PGD slot.
