e399a78960 V4L/DVB (9463): Make delivery system standalone.
Eventhough the delivery system is made standalone, DVBFE_SET_DELSYS
needs to be set as the very first operation, for a multistandard frontend

Splitting delivery system out as a new ioctl, makes things a bit more
easier to understand.

b91a7cb026 V4L/DVB (9462): Allow specifying clock per device
Optimizations galore: Blistering barnacles! The KNC1 and friends
like 90 Mhz clock much better rather than running at a higher
throttle, for almost similar hardware. he exact cause unknown,
possibly due to a lower voltage applied for the demod power supply.

763fbaf65a 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

27a330d124 V4L/DVB (9442): Revert back previous change to 90MHz
Note:
* At High Symbol Rates we do not have enouph machine cycles to handle the
  incoming symbols and hence might run into problems at the very end of the
  specified definition
* Most of the equations have been calculated for a master clock of 99 MHz,
  running at 90MHz, raises lot of issues such as the need to recalculate
  all of them , which is eventually very painful.

which should have happenend in the DVB-S2 mode only, but reading it as it is
for the other delivery systems causes nothing to say but LOCK_LOST, which

54c358fc23 V4L/DVB (9381): On the KNC1 cards the CLOCK is clamped to a maximum limit of 90MHz, eventhough
not limited in hardware, this causes instabilities at a higher clock due to
issues such as thermal, also the divider wraps around, which causes the
demodulator core to actually run at a lower frequency. This needs to be
empirically tested whether it affects other cards. If found necessary, this
parameter needs to be moved out to the config struct such that it can be made
hardware dependant.

Reducing the CLOCK from 99MHz to 90MHz improved the acquisition time taken on
the KNC1 cards and hence such a change.
