V4L/DVB (4314): Set the Auxiliary Byte when tuning LG H06xF in analog mode

With the LG H06xF tuners, an auxiliary byte must be sent after the
standard four-byte i2c sequence. The code that does this is currently in
the wrong place, causing random bytes to be written to the tuner over
i2c in the set_type function.
This patch moves this code from set_type to default_set_tv_freq.
