[V2,1/3] media: dvb-core: Store device structure in dvb_register_device

  From: Jasmin Jessich <jasmin@anw.at>

The device created by device_create in dvb_register_device was not
available for DVB device drivers.
Added "struct device *dev" to "struct dvb_device" and store the created
device.

Hi!

Please hold on in merging this series, because I have to investigate a hint
I got related to the buffer size handshake of the protocol driver:
