V4L/DVB (9590): Add registration for Pinnacle 80e ATSC tuner

Browse Source 
Add registration for Pinnacle 80e ATSC tuner

Register the em2874 based Pinnacle 80e device.  Note that support for this
device also requires the new drx-j driver (which is not available yet)

Thanks for Ray Lu from Empia for providing the em2874 datasheet.
Thanks to Joerg Schindler from Pinnacle for providing sample hardware.
Thanks to Rainer Miethling from Pinnacle for providing engineering support.
