V4L/DVB (8654): cxusb: add support for DViCO FusionHDTV DVB-T Dual Digital 4 (rev 2)

Add support for revision 2 of the DViCO FusionHDTV DVB-T Dual Digital 4
which has new tuners and demodulators (2 x DIB7070p). With this patch
both DVB reception and IR works.

The dib7000p driver currently hardwires the output mode to
OUTMODE_MPEG2_SERIAL regardless of what we ask for. Modify it to allow
OUTMODE_MPEG2_PAR_GATED_CLK to be set. Longer term we should remove the
check completely and set the output mode correctly in all the callers.

Add Kconfig bits to ensure the dib7000p and dib0070 modules are enabled.
It would be nice to only do this for the !DVB_FE_CUSTOMISE case, but
this is what the other DIB7070 module does (there are a number of
module dependencies in the attach code).
