Add analog tuning support to tda827x dvb_frontend tuner module.
Convert tda8290 module back to native tuner interface.
The tda8290 analog demodulator will be handled the same way as tda9887.
The tuner.ko module (tuner-core) will pass commands to tda8290 via the
tuner_operations interface. tda8290 will communicate with tda827x via
the dvb_frontend interface, while passing a pointer to a private data
structure.

When the tuner is attached, the tda10046 is not initilized yet, so it
is searching for its firmware. If the tuner is attached to the tda10046
silent i2c port, a bus collision can occur. Now the version is probed
during the first init or sleep call.

- The i2c data buffer in tda827xa_set_params was 1 byte too short
- saa7134-dvb now gives an error mesage if tda827x could not be attached
- coding style fix in tda1004x.c

The parameters for minimum and maximum frequency were missing.
Also added mail addresses of the module authors.

This change sets the tda827x to sleep mode right after attach in dvb
mode. It is just to save power. For the same reason, the ADC of the
tda10046 gets turned off in sleep mode.
