Matthew Wilcox (Oracle) a6d01af08b loongarch: implement the new page table range API
Add update_mmu_cache_range() and change _PFN_SHIFT to PFN_PTE_SHIFT.  It
would probably be more efficient to implement __update_tlb() by flushing
the entire folio instead of calling __update_tlb() N times, but I'll leave
that for someone who understands the architecture better.
