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.

If we are already at the desired modulation, there is no need to reconfigure
the demod (at a tuning time cost)
Note that this change revealed that although the datasheet says the demod
starts out in VSB-8 mode, the first tuning was failing consistently unless
we went through the work of setting the registers. So add a field to denote
this case so we always do the enable_frontend call, even if the first tuning
request is for VSB-8.

If you instruct the tuner to change frequencies, it can take up to 2500ms to
get a demod lock. By performing a soft reset after the tuning call (which
is consistent with how the Pinnacle 801e Windows driver behaves), you get
a demod lock inside of 300ms

Christophe divulged the following:
"Since 8PSK (and higher mod) signals are very likely to have pilot symbols,
pilot_auto should start with pilot_on for 8PSK.
And since QPSK signals are unlikely to have pilot, pilot_auto should start
with pilot_off for QPSK.
Without the patch:
QPSK tuning delay: ~100ms
8PSK tuning delay: ~900ms
with patch:
QPSK tuning delay: ~100ms
8PSK tuning delay: ~100ms
"
This patch does as Cristophe asks. In emulated auto-pilot we
choose pilot-on for tuning PSK_8 and pilot-off for
tuning QPSK.

Add some sanity checking to data input via S2API to the cx24116 demod.
This patch is valid for both s2-mfe and s2.
It was found when testing KAFFEINE with S2API support that invalid
modulation modes amongst other parameters were being delivered to
the demod. In order to debug this sanity checking has been added.
An example session would involve kaffeine setting QAM_AUTO when
querying DVB-T, then later when trying to tune to DVB-S this
cached value would be presented in error.
