media: cedrus: Set the platform driver data earlier

Browse source 
commit 708938f849 upstream.

The cedrus_hw_resume() crashes with NULL deference on driver probe if
runtime PM is disabled because it uses platform data that hasn't been
set up yet. Fix this by setting the platform data earlier during probe.
