[media] tda18271: delay IR & RF calibration until init() if delay_cal is set 



if the configuration option 'delay_cal' is set, delay both IR & RF
calibration until init() is called.
both module option 'cal' or configuration option 'rf_cal_on_startup'
will override this delay. it makes no sense to mix 'delay_cal' with
'rf_cal_on_startup' as these options conflict with each other.
