[PATCH v1 2/6] dt-bindings: firmware: arm,scmi: Introduce property max-rx-timeout-ms

[Cristian Marussi]

From: Peng Fan <peng.fan@xxxxxxx>

System Controller Management Interface(SCMI) firmwares might have different
designs depending on the platform: the maximum receive channel timeout
value might vary depending on the specific underlying hardware and firmware
design choices.

Introduce the general property max-rx-timeout-ms property to describe the
transport needs of a specific platform design.
