Using SCMI under OP-TEE (uboot)

[Dan Carpenter]

SCMI over OP-TEE is not working for me on u-boot and I was wondering
how other people use it.

It fails with:
scmi-over-optee scmi0: failed to probe base protocol

It's an ordering problem.  The scmi_optee_probe() function tries to
call open_channel() which tries to tee_find_device() but the
tee_pre_probe() has not been called yet.
