sdm845: update kernel config and ucm confs
The config file was not up-to-date with the sdm845 kernel repo. Fix it. This should also fix the missing Pixel 3 touchscreen config (https://gitlab.com/postmarketOS/pmaports/-/merge_requests/5514#note_2143705009) and general pmOS kconfig checks. Also, update ucm conf to include pixel3 speaker support.
