[PATCH v1] arm64: dts: verdin-imx8mm: fix dahlia audio playback

[Francesco Dolcini]

From: Emanuele Ghidoli <emanuele.ghidoli at toradex.com>

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.

Fixes: 6a57f224f734 ("arm64: dts: freescale: add initial support for verdin imx8m mini")
