[PATCH] ASoC: fix boolreturn.cocci warnings

[kbuild test robot]

From: Fengguang Wu <fengguang.wu@xxxxxxxxx>

sound/soc/codecs/tda7419.c:151:9-10: WARNING: return of 0/1 in function 'tda7419_vol_is_stereo' with return type bool

 Return statements in functions returning bool should use
 true/false instead of 1/0.
Generated by: scripts/coccinelle/misc/boolreturn.cocci

Fixes: d811df0fabec ("ASoC: add tda7419 audio processor driver")
