Daniel Scheller b9a92f62c5 media: ddbridge: fix buffer overflow in max_set_input_unlocked() 
Picked up code parts introduced one smatch error:

  drivers/media/pci/ddbridge/ddbridge-maxs8.c:163 max_set_input_unlocked() error: buffer overflow 'dev->link[port->lnr].lnb.voltage' 4 <= 255

Fix this by clamping the .lnb.voltage array access to 0-3 by "& 3"'ing
dvb->input.

Daniel Scheller bb4cec96e5 media: ddbridge: support MaxLinear MXL5xx based cards (MaxS4/8) 
This enables MaxS4/S8 and Octopus Max card support in ddbridge by adding
glue code into ddbridge-core, having another PCI ID, and have the LNB IC
control code (and all other MaxS4/8 related code) in ddbridge-maxs8.c
(rather than another ~400 LoC in ddbridge-core.c like it's done in the
original vendor driver package).
