Subject: [PATCH 1/7] arm64: dts: freescale: imx95: set max-rx-timeout-ms

From: Peng Fan <peng.fan@....com>

With 'max-rx-timeout-ms' property added in 'Documentation/devicetree/
indings/firmware/arm,scmi.yaml', set the value for i.MX95.

NXP i.MX95 SCMI Firmware designation does not allow timeout, it will not
recover if the Agents use timeout design. So set a large value (5000ms)
here.
