From: Peng Fan <peng.fan@xxxxxxx> System Controller Management Interface(SCMI) firmwares might have different designs by SCMI firmware developers. So the maximum receive channel timeout value might also varies in the various designs. So introduce property mbox-rx-timeout-ms to let each platform could set its own timeout value in device tree.
