alsa-ucm-conf-google-kukui: improvements for mt8183 ucm

Krane doesn't have a headphone jack, which caused audio server issues for me. Add a check to only enable the headphone and headset mic device on non-Krane boards. Also improve the formatting and remove ChromeOS-specifc options.

I've tested this on Krane but I don't have any other mt8183 devices. Can someone with mt8183_da7219_rt1015p and someone with mt8183_mt6358_ts3a227_max98357 test this?
