arm64: dts: mediatek: mt8390-genio-common: Add delay codec for DMIC
The signal from the dual digital microphones connected to the DMIC_BE
takes 30ms to settle after being enabled. Add a dmic-codec with
corresponding wakeup-delay-ms to prevent an initial "pop" sound when
recording with the microphones.
