drivers/arm/scmi: allow use of multiple SCMI channels
On systems that have multiple platform components that can interpret the SCMI messages, there is a need to support multiple SCMI channels (one each to those platform components). Extend the existing SCMI interface that currently supports only a single SCMI channel to support multiple SCMI channels. Change-Id: Ice4062475b903aef3b5e5bc37df364c9778a62c5 Signed-off-by: Aditya Angadi <aditya.angadi@arm.com>
