media: cedrus: Set the platform driver data earlier

Browse Source 
commit 708938f8495147fe2e77a9a3e1015d8e6899323e 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.
