[PATCH 2/4] ASoC: mediatek: mt8183: Fix APLL enable error handling

[phucduc.bui@gmail.com]

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

Currently, the mt8183_apll*_enable() functions call mux_setting(afe, true)
but do not check its return value to handle failures.

In addition, the cleanup paths of mt8183_apll*_enable() do not call
mux_setting(afe, false) when the enable operation fails, while the
mt8183_apll*_disable() functions do.

Add error handling for apll*_mux_setting() and call mux_setting(afe, false)
in the cleanup paths when mt8183_apll*_enable() fails.
