firmware: arm_scmi: Move scmi protocols registration into the driver
In preparation to enable building SCMI as a single module, let us move the SCMI protocol registration call into the driver. This enables us to also add unregistration of the SCMI protocols. The main reason for this is to keep it simple instead of maintaining it as separate modules and dealing with all possible initcall races and deferred probe handling. We can move it as separate modules if needed in future.
