[RFC PATCH 2/7] firmware: arm_scmi: Document that max_msg is a per channel type limit

From: Peter Hilber
Date: Fri Sep 18 2020 - 12:53:58 EST

From: Igor Skalkin <igor.skalkin@xxxxxxxxxxxxxxx>

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.
