The V4L2 core sets the format description and flags 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. And in am437x-vpfe.c drop an unnecessary f->type assignment in vpfe_enum_fmt().
