Cristian Marussi 92d755b708 firmware: arm_scmi: Reject clear channel request on A2P ...

BugLink: https://bugs.launchpad.net/bugs/2101915

[ Upstream commit a0a18e91eb3a6ef75a6de69dc00f206b913e3848 ]

The clear channel transport operation is supposed to be called exclusively
on the P2A channel from the agent, since it relinquishes the ownership of
the channel to the platform, after this latter has initiated some sort of
P2A communication.

Make sure that, if it is ever called on a A2P, is logged and ignored.
