[PATCH 2/7] ASoC: mediatek: mt8188: mt8188-afe-clk: Handle tuner clock enable errors

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

Clock enable errors are currently ignored when enabling the APLL
and tuner clocks.
Check the return values and roll back the APLL clock if the tuner
clock fails to enable.

Fixes: f6b026479b13 ("ASoC: mediatek: mt8188: support audio clock control")
