V4L/DVB (11745): pvrusb2: Update to work with upcoming ir_video changes in v4l-dvb core

The ir-kbd-i2c module is about to be updated to match the new style
i2c binding model.  These pvrusb2 changes maintain compatibility with
that change.  Note that this does not actually break anything even
without the expected ir-kbd-i2c changes yet because previously the
pvrusb2 didn't autoload ir-kbd-i2c anyway.
