v4l2-common: added v4l2_i2c_tuner_addrs()
From: Hans Verkuil <hverkuil@xs4all.nl>
Add v4l2_i2c_tuner_addrs() to obtain the various I2C tuner addresses.
This will be used in several drivers, so make this a common function
as we do not want to have these I2C addresses all over the place.
Priority: normal
