firmware: arm_scmi: Validate PCC shared memory signature
Validate the PCC shared memory signature when setting up an SCMI PCC
channel.
Reject channels whose shared memory signature does not encode
PCC_SIGNATURE combined with the PCC subspace ID, so misconfigured
firmware is caught before the transport starts using the shared memory
region.
