microblaze: implement the new page table range API
Rename PFN_SHIFT_OFFSET to PTE_PFN_SHIFT. Change the calling convention
for set_pte() to be the same as other architectures. Add
update_mmu_cache_range(), flush_icache_pages() and flush_dcache_folio().
[arnd@arndb.de: mark flush_dcache_folio() inline]
