Fixing of DW SPI which was broken by
commit 07906b3dad15 ("ARC: Switch to generic accessors")
lead me to several fixes in ARC IO accessors code.

Eugeniy Paltsev (3):
  ARC: IO: add volatile to accessors
  ARC: IO: add compiler barriers to IO accessors
  ARC: IO: add MB for __raw_* memory accessors
