Andreas Regel 96506a5086 V4L/DVB (13976): [STV090x] Added mutex protection around tuner I2C access.
With this change it is possible to have the same I2C address for both tuners.

Andreas Regel 97f7a2ae1a V4L/DVB (13975): [STV090x] Added internal structure with shared settings and data.
As the STV0900 features two demodulation paths in one chip there is
some information used by both instances of the driver when used in
dual mode. This information is now shared in an internal structure
referenced by I2C adapter and address.

Do initialisation of the demodulator only once when used in dual mode.
Moved global mutex demod_lock to internal structure.
Moved dev_ver and mclk to internal structure.
Removed unused tuner_refclk from stv090x_state.

Manu Abraham 27d4032143 V4L/DVB (11682): STV0900/STV0903: Add support for Silicon cut >= 3
1. Support Silicon Cut >= 3.0
2. Remove support for obsolete cuts: 1.0. 1.1. 1.2
3. Try to catch more error cases

Driver doesn't now attach to obsolete silcon cuts, It just simply quits.
Results in code simplification, with removal of the obsolete cuts.
