media: cx231xx: Add i2c device analog tuner support
The boards listed below use i2c device drivers and have
tuner_type equal TUNER_ABSENT. This means additional support
is required to enable the analog tuning capability, a case
statement is used to identify these models.
Models with analog tuning enabled:
- CX231XX_BOARD_HAUPPAUGE_930C_HD_1114xx (tested)
- CX231XX_BOARD_HAUPPAUGE_935C (tested)
- CX231XX_BOARD_HAUPPAUGE_955Q (tested)
- CX231XX_BOARD_HAUPPAUGE_975 (tested)
- CX231XX_BOARD_EVROMEDIA_FULL_HYBRID_FULLHD (untested)
The EvroMedia model was added, since it uses the si2157
tuner and the board profile claims it has analog inputs.
