The STM32MP135F-DK support in barebox has bitrotted, because of changes
to the upstream device tree: The root of the clock tree is now provided
by OP-TEE over SCMI for which no support exists in barebox, so drivers
requesting clocks will defer indefinitely, including the console device.
A series adding OP-TEE SCMI support will follow, but for now, let's
ensure that console registration isn't deferred in such a case.
