[PATCH] ASoC: mediatek: mt6358: add missing EXPORT_SYMBOLs

[Jiaxin Yu]

Fixes the following build errors when mt6358 is configured as module:

>> ERROR: modpost: "mt6358_set_mtkaif_protocol"
>> [sound/soc/mediatek/mt8186/mt8186-mt6366-rt1019-rt5682s.ko] undefined!
>> ERROR: modpost: "mt6358_set_mtkaif_protocol"
>> [sound/soc/mediatek/mt8186/mt8186-mt6366-da7219-max98357.ko] undefined!
