pci_dma_mapping_error can't be used for pci_alloc_consistent
(pci_dma_mapping_error is for dma_map_single and dma_map_page).

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.

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.

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

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.

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.
