ASoC: rsnd: rsnd_write() / rsnd_bset() uses regmap _force_ function
Some R-Car sound requests picky register access which needs *force*
register write.
Some status register needs to set 1 to clear status, but we might
read 1 from its register. In such case, current regmap does nothing
and driver will be forever loop
To reduce code complexity, this patch uses regmap _force_
function for all register access.
