[PATCH] ASoC: mediatek: mt8192: Fix build failure

[Sudip Mukherjee]

A build of arm64 allmodconfig with next-20201105 fails with the error:
ERROR: modpost: "mt8192_afe_gpio_request" undefined!
ERROR: modpost: "mt8192_afe_gpio_init" undefined!

Export the symbols so that mt8192-mt6359-rt1015-rt5682.ko finds it.
