[PATCH 14/15] ASoC: mediatek: mt8192: Propagate errors in I2S DAI DAPM event handlers

[phucduc . bui]

From: bui duc phuc <phucduc.bui@xxxxxxxxx>

Currently, DAPM event handlers in mt8192-dai-i2s.c ignore return values
from mt8192_afe_gpio_request(), mt8192_apll1_enable(),
mt8192_apll2_enable(), and mt8192_mck_enable(). If GPIO configuration or
clock setup fails during DAPM events, the error is silently ignored.

Fix this by checking and propagating error codes properly in all I2S DAI
DAPM event handlers.

Fixes: 2c37b4ed730b ("ASoC: mediatek: mt8192: support i2s in platform driver")
