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.

The Bug was found by Arvo Jarve <arvo@softshark.ee>

It was a wonder how it worked in the case with this bug,
STM verified this that this nibble was in fact insignificant
and can be ignored.

But still we need to fix all inconsistencies.

1e3d8abe6d V4L/DVB (9433): Limit bandwidth with a 3dB response fall
In this case, we will be sure that there exists a carrier
and the center frequency would be simply f1 - f2. In such
a circumstance, the TR loop is simplified to doing a simple
check for timing, rather than searching for the same.

b655b6cbc9 V4L/DVB (9430): stb0899: avoid parameter overwriting
BUG! Setting CRL parameter overwrote the CR Algorithm type,
eventually leading to wrong search algorithm to be employed in
the DVB-S carrier loop optimization.

Symptom: Once the CR optimization stage is passed either way, in
a successful or failed manner, the very next carrier search will
fail, due to no Carrier Search Algorithm specified.
