Stefan Pöschel 9e422f64fa [media] af9035: fix dual tuner detection with PCTV 79e
The value 5 of the EEPROM_TS_MODE register (meaning dual tuner presence) is
only valid for AF9035 devices. For IT9135 devices it is invalid and led to a
false positive dual tuner mode detection with PCTV 79e.
Therefore on non-AF9035 devices and with value 5 the driver now defaults to
single tuner mode and outputs a regarding info message to log.

This fixes Bugzilla bug #118561.
