V4L/DVB (8068): cx18: Add I2C slave reset via GPIO upon initialization
cx18: Add I2C slave reset via GPIO upon initialization. One user,
Michael <msd4824@yahoo.com>, has reported this allows his HVR-1600 EEPROM to
be consistently recognized when using (long,) 100 msec delays. The delays in
this commit are nominal (10 & 40 msec) and need testing/tuning on boards with
I2C problems to find the right values.
