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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
