ASoC: mediatek: Add common snd_soc_ops .startup() callback

MediaTek platforms are typically setting PCM rate and channels
constraints for playback, capture and HDMI/DisplayPort playback:
commonize the startup callback by adding the PCM constraints data
to the mtk_platform_card_data structure and by reusing the common
mtk_soundcard_startup() function for all of them by getting back
the parameters from the aforementioned struct.
