ASoC: mediatek: mt6359: Fix unexpected error in bind/unbind flow

Browse Source 
mt6359-sound is a MFD driver. Because its regmap is retrieved from its
parent, it shouldn't be freed in mt6359-sound driver.

snd_soc_component_exit_regmap() will do regmap_exit(), this results in
unexpected results if sound card unregister flow is invoked when users
try to bind/unbind audio codec.

Remove the usage of snd_soc_component_exit_regmap(). Instead, set
component->regmap = NULL in the component remove function.
