Nack.

Nothing wrong with probe deferring. It is there to ensure the order
the drivers probe in is correct.

Plus, moving it to arch_initcall won't solve anything.

fw_devlink will not stop the driver from probing if there is no provider
that this driver is waiting for. And if there is a provider that is
needed by this clock controller, moving it to arch_initcall won't
magically skip waiting for the provider anyway.
