regmap: 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.
