ASoC: mediatek: mt8192-mt6359: Fix error handling in MTKAIF calibration
mt8192_mt6359_mtkaif_calibration() ignored the return values of
pm_runtime_get_sync() and mt8192_afe_gpio_request(), which could
leave PM runtime references or GPIO state unbalanced on failure.
Switch to pm_runtime_resume_and_get(), check each GPIO request,
and unwind on error.
Fixes: 18b13ff23fab ("ASoC: mediatek: mt8192: add machine driver with mt6359, rt1015 and rt5682")
