V4L/DVB (13216): tda18271: initialize tuner during set_config if rf_cal_on_startup is set
If rf_cal_on_startup is enabled in the structure passed into
tda18271_set_config, and the cal module option isn't disabled,
then we should run the initialization and calibration procedures
during the tda18271_set_config function call.
