V4L/DVB (6136): dvb_frontend: add get_rf_strength function pointer to dvb_tuner_ops
Add get_rf_strength function pointer to dvb_tuner_ops, so that rf signal
strength can be read directly from the tuner driver by the dvb demodulator
driver and / or the analog tuning system.
This is an internal api addition -- userspace is not affected.
