Sv32 supports 2^34 physical memory under RV32. Previously, pmp only supported
 2^Xlen physical memory, and the physical memory was limited to 4G under rv32.
 This patch hopes to remove this limitation.

Xiang W (2):
  lib: sbi: Improve pmp_get/pmp_set
  lib: sbi: Using word addresses in memregion, missing right shift 2 bits

v2:
- Rebased on master
- Fixed walign when calling sbi_domain_root_add_memrange
