arm64: dts: verdin-imx8mp: fix dahlia audio playback
Set optional `simple-audio-card,mclk-fs` parameter to ensure a proper
clock to the wm8904 audio codec. Without this change with an audio
stream rate of 44.1 kHz the playback is completely distorted.
Related-to: ELB-4579
Upstream-Status: Inappropriate [other]
This commit applies to downstream only, since there is no audio support upstream.
