Pull regmap fix from Mark Brown:
 "One more fix for v6.4

  The earlier fix to take account of the register data size when
  limiting raw register writes exposed the fact that the Intel AVMM bus
  was incorrectly specifying too low a limit on the maximum data
  transfer, it is only capable of transmitting one register so had set a
  transfer size limit that couldn't fit both the value and the the
  register address into a single message"
