Subject: [PATCH] sound: soc: mediatek: mt8192: fix modpost ERROR

When enabling CONFIG_SND_SOC_MT8192_MT6359_RT1015_RT5682=m the following
error shows up:

ERROR: modpost: "mt8192_afe_gpio_request"
[sound/soc/mediatek/mt8192/mt8192-mt6359-rt1015-rt5682.ko] undefined!
ERROR: modpost: "mt8192_afe_gpio_init"
[sound/soc/mediatek/mt8192/mt8192-mt6359-rt1015-rt5682.ko] undefined!

Fix the link error by export the symbols mt8192_afe_gpio_init and
mt8192_afe_gpio_request.

Fixes: 18b13ff23fab ("ASoC: mediatek: mt8192: add machine driver with mt6359, rt1015 and rt5682")
