cx18: Add I2C slave reset via GPIO upon initialization
From: Andy Walls <awalls@radix.net> 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. Signed-off-by: Andy Walls <awalls@radix.net>
