input_dvb: Allow automatic detection of DVB parameters

We've experienced glitches where the NIT does not match the transmission
parameters, and bugs in the kernel where the values we read back from the
frontend don't match the transmission.

To get round this, we've changed scan to store BANDWIDTH_AUTO and equivalents
in the channels.conf file. Update input_dvb to cope with automatic detection
of all frontend parameters.
