ASoC: mediatek: Fix UBSAN warning.
In sound/soc/mediatek/common/mtk-afe-fe-dai.c, when xxx_reg is -1, it's a no-op to call mtk_regmap_update_bits, but since both xxx_reg and xxx_shift are set to -1, the (1 << xxx_shift) in the argument would trigger a UBSAN warning. Fix the warning by setting those xxx_shift to 0 instead. Note that since the code explicitly checks .mono_shift >= 0 and .fs_shift >= 0 before using them in '<<' operator, those two members are not set to 0.
