arc: implement the new page table range API
Add PFN_PTE_SHIFT, update_mmu_cache_range(), flush_dcache_folio()
and flush_icache_pages().
Change the PG_dc_clean flag from being per-page to per-folio (which means
it cannot always be set as we don't know that all pages in this folio were
cleaned). Enhance the internal flush routines to take the number of pages
to flush.
