bytcr-rt5651: Fix high noise level + soft input on DMIC
The DMIC needs to have the DMIC ASRC enabled, otherwise capturing audio
from it results in mostly capturing noise + the actual recorded voice
very soft in the background of the noise.
This has been tested on a Point of View P1006W v1.0 tablet, which is the
only RT5651 X86 device using a DMIC that I am aware of.
