Current debug messages at cx24123 are next to useless, since they don't
print the values sent/read to registers. With this patch, debug=1 will
show comprehensive messages. debug=2 will show also read/write operations
at I2C bus.

- fixed the reception of channels with low symbol rates.
( The VGA1 and VGA2 offsets recommended by cx24109 docs for
symbol rates from 1 to 5 MSps do not work. I changed them
to values found experimentally. The charge pump current
and FILTUNE voltage are now set to values recommended in
the docs. This improves reception for symbol rates < 15 MSps.
The values written in the SYSSymbolRate registers are calculated
with better precision. )
- fixed the cx24123_get_fec() function. It was returning the values
for DCII mode.
- removed some unused variables

- Add support for KWorld DVB-S 100, based on the same chips as Hauppauge
Nova-S Plus (CX23883/CX24123/CX24109), without the Intersil ISL6421,
which is used for LNB control.
- LNB voltage and tone are controled by LNBDC and LNBTone bits from
register 0x29 of the CX24123 demodulator.
- The MO_GP0_IO register from CX23883 is used to turn LNB power on and off.
