ASoC: codecs: wsa881x: do not set can_multi_write flag
[ Upstream commit 6e7a6d4797ef521c0762914610ed682e102b9d36 ]
regmap-sdw does not support multi register writes, so there is
no point in setting this flag. This also leads to incorrect
programming of WSA codecs with regmap_multi_reg_write() call.
This invalid configuration should have been rejected by regmap-sdw.
