ASoC: codecs: wcd938x-sdw: do not set can_multi_write flag
[ Upstream commit 2d7c2f9272de6347a9cec0fc07708913692c0ae3 ]
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.
