V4L/DVB (12293): b2c2: Use dvb-pll for Skystar2 rev 2.3 and rev 2.6
The code in skystar23_samsung_tbdu18132_tuner_set_params() and samsung_tbmu24112_tuner_set_params() is equivalent to what the dvb-pll code does. There could be an issue because the dvb-pll code will probe to check for the tuner, while the previous code didn't do any checks.
