firmware: arm_scmi: Make optee support sync_cmds_completed_on_ret
Declare each OPTEE SCMI channel as not having a completion_irq so as to
enable polling mode and then enable also .sync_cmds_completed_on_ret flag
in the OPTEE transport descriptor so that real polling is itself
effectively bypassed on the rx path: once the optee command invocation has
successfully returned the core will directly fetch the response from the
shared memory area.
Remove OPTEE SCMI transport specific .poll_done callback support since
real polling is effectively bypassed when .sync_cmds_completed_on_ret is
set.
Add OPTEE SCMI transport specific .mark_txdone callback support in order to
properly handle channel locking along the tx path.
