V4L/DVB (12312): stv0900: fix i2c repeater configuration must be set to manual 



In automatic mode every stop event on SDA line ends repetition.
However, in  NetUP Dual card on the same i2c bus we have several devices.
If someone using both adapters to lock simultaneously or working with CAM interface
during lock procedure, it lead to end repetition prematurely quite often.
Set stv0900 i2c repeater to manual mode prevents such situation.
