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.

According to adi,adv7533.yaml, the order for the reg and reg-names entries
must be: main, edid, cec, and packet.
Fix it accordingly to remove the following dt-schema warnings:
hdmi@3d: reg-names:1: 'edid' was expected
hdmi@3d: reg-names:2: 'cec' was expected

'sound-dai' should contain only 'sai5'. Remove the extra entry to
fix the following schema warning:
imx8mm-beacon-kit.dtb: sound-hdmi: simple-audio-card,cpu:sound-dai: [[110], [0]] is too long
from schema $id: http://devicetree.org/schemas/sound/simple-card.yaml#
