media: venus: drop bogus probe deferrals

The encoder and decoder platform devices are registered by the venus
driver as children of the venus device, but even if someone were to mess
this up no amount of probe deferring is going to conjure up a parent.

Relatedly, the venus driver sets its driver data before registering the
child devices and if this ever breaks we want to learn about it by
failing probe.
