Rename pte_prot_nowrite to pte_clear_modify

risc-v: fix ref/mod emulation PTE handling.

The previous code has zero chance of working and now that pmap_test_mod_ref
exists it can prove this code is correct.

Annotate page table/directory entry pointer deference with
atomic_load_relaxed to ensure memory operations aren't fused
or torn.

mi pmap: support code for HW updated referenced and modified PTE bits

Previously the MI PMAP would rely on mod/ref emulation to update
mdpg_attrs if a page was modified or referenced. Now support checking
each mapping's HW modified PTE bits (and updating mdpg_attrs).
