Merge branch '2023-10-24-assorted-general-fixes-and-updates'

- Remove common.h in a number of places and make checkpatch.pl complain
  about its use in all cases, allow the mbr command to handle 4 primary
  partitions, fix an issue with the pstore command, fix a problem with
  cli parsing of escape sequences, remove and ignore more files, allow
  for the serial port to be flushed with every print (for debugging),
  and add SCMI power domain support.
