V4L/DVB (3848): Convert cx22702 to refactored tuner code
Convert to tuner_ops calls. Remove pll function pointers from structure. Remove unneeded tuner calls. Add i2c gate control function. Remove dvb-pll support - done elsewhere now. Signed-off-by: Andrew de Quincey <adq_dvb@lidskialf.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
