ucm2: Toradex: apalis-imx8: Set default values for input and output devices

Browse source 
Add EnableSequence/DisableSequence entries for the Mic input device. Align
BootSequence with other Toradex NXP module configurations. Remove Lineout
from the BootSequence, as the codec Lineout output pin is not connected on
the Apalis iMX8.

Previously uninitialized configurations were set unpredictably at boot, causing
high-noise input/output behavior. Set these configs explicitly to ensure the
sound card starts in a known working state.
