arm: implement the new page table range API
Add set_ptes(), update_mmu_cache_range(), flush_dcache_folio() and
flush_icache_pages(). Change the PG_dcache_clear flag from being per-page
to per-folio which makes __dma_page_dev_to_cpu() a bit more exciting.
Also add flush_cache_pages(), even though this isn't used by generic code
(yet?)
