Hans Verkuil 2169e6daa1 media: media/pci: don't set description for ENUM_FMT 
The V4L2 core sets the description for the driver in order to ensure
consistent naming.

So drop the strscpy of the description in drivers. Also remove any
description strings in driver-internal structures since those are
no longer needed.
