Mark Johnston 8c88d17fa5 riscv: Port improvements from arm64/amd64 pmaps, part 1
- When promoting, do not require that all PTEs all have PTE_A set.
  Instead, record whether they did and store this information in the
  PTP's valid bits.
- Synchronize some comments in pmap_promote_l2().
- Make pmap_promote_l2() scan starting from the end of the 2MB range
  instead of the beginning.  See the commit log for 9d1b7fa31f for
  justification of this, which I believe applies here as well.
