arm64: dts: imx8mn-beacon: Set SAI5 MCLK direction to output for HDMI audio

Browse Source 
[ Upstream commit a747c4dd2a60c4d0179b372032a4b98548135096 ]

The HDMI bridge chip fails to generate an audio source due to the SAI5
master clock (MCLK) direction not being set to output. This prevents proper
clocking of the HDMI audio interface.

Add the `fsl,sai-mclk-direction-output` property to the SAI5 node to ensure
the MCLK is driven by the SoC, resolving the HDMI sound issue.
