[PATCH v3 05/16] ASoC: mediatek: mt8195: Fix main clock error handling

[phucduc.bui at gmail.com]

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

Check the return values of clock enable functions and propagate
errors to the caller.

Disable previously enabled clocks on failure to match the
main clock disable sequence.

Fixes: 6746cc858259 ("ASoC: mediatek: mt8195: add platform driver")
