Subject: [PATCH] firmware: arm_scmi: Document that max_msg is a per channel
 type limit

struct scmi_desc.max_msg specifies a limit for the pending messages.
This limit is a per SCMI channel type (tx, rx) limit. State that
explicitly in the inline documentation. The following patch will add an
op to override the limit per channel type.
