Subject: [PATCH 1/2] ASoC: codecs: wsa883x: do not set can_multi_write flag

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.

Fixes: 43b8c7dc85a1 ("ASoC: codecs: add wsa883x amplifier support")
