[PATCH] dvb: flexcop: add BCM3510 ATSC frontend support for Air2PC card

Browse source 
Added support for the Broadcom BCM3510 ATSC (8VSB/16VSB & ITU J83 AnnexB FEC
QAM64/256) demodulator used in the first generation of Air2PC ATSC
PCI-cards/USB-boxes made by B2C2.

*
* The driver works also with QAM64 DVB-C, but had an unreasonable high
* UNC. (Tested with the Air2PC ATSC 1st generation)
*
