Fix I2C bridge error in zl10353
Fix I2C bridge error in zl10353 if no tunner attached to internal I2C
bus of zl10353 chip.
When set enable bridge from internal I2C bus to the main I2C bus
(saa7134) the main I2C bus stopped very hardly. No any communication. In
our next board we solder additional resistors to internal I2C bus.
