V4L/DVB (12867): tda18271: ensure that configuration options are set for multiple instances

Browse source 
For the case of multiple tuner instances, ensure that non-default
configuration options are saved into the driver's state.

This resolves an issue where a configuration option may not be
carried into the driver if the analog side of a hybrid driver
initializes before the digital side.
