V4L/DVB (6230): dvb-pll: add module option to force dvb-pll desc id (for
debug use only)
Add a module option to force the dvb-pll module to use an alternate dvb-pll
description without having to recompile the kernel.
Having a module option like this is useful in some cases, where the vendor
may release an alternate revision of the hardware using a different tuner,
but without changing the pci subsystem / usb device ids.
This option is intended for debugging purposes _only_.
