Subject: V4L/DVB (9443): Bug: Bandwidth calculation

Bug #1: The 5 tap equaliser is set to correct simple perturbations
like reflections on the IF cable for DVB-S. In the case of DVB-S2
a more powerful equalizer is used to correct the filter group delay
allowing the bandwidth to be reduced by a factor of 1/3

Bug #2: The ZIF tuner takes badwidth to be set in Hz

Subject: V4L/DVB (9457): Optimization, Fix a Bug

* cut down some I/O operations by disabling "disable gate"
* budget_av was left with the gate open, thereby more susceptible
to RF interference due to I/O operations
