Sibi Sankar 9429f3e816 firmware: arm_scmi: Ensure that the message-id supports fastchannel ... commit 94a263f981 upstream. Currently the perf and powercap protocol relies on the protocol domain attributes, which just ensures that one fastchannel per domain, before instantiating fastchannels for all possible message-ids. Fix this by ensuring that each message-id supports fastchannel before initialization. Logs: | scmi: Failed to get FC for protocol 13 [MSG_ID:6 / RES_ID:0] - ret:-95. Using regular messaging | scmi: Failed to get FC for protocol 13 [MSG_ID:6 / RES_ID:1] - ret:-95. Using regular messaging | scmi: Failed to get FC for protocol 13 [MSG_ID:6 / RES_ID:2] - ret:-95.
