Pull RISC-V cleanups from Palmer Dabbelt:
 "This contains a handful of small cleanups.

  The only functional change is that IRQs are now enabled during
  exception handling, which was found when some warnings triggered with
  `CONFIG_DEBUG_ATOMIC_SLEEP=y`.

  The remaining fixes should have no functional change: `sbi_save()` has
  been renamed to `parse_dtb()` reflect what it actually does, and a
  handful of unused Kconfig entries have been removed"
