reef: make corrections to I2C GPIOs in gpio.inc

Browse Source 
There were a few things wrong with the way I2C pins were originally
set up:
- EC_I2C_SENSOR_SCL was moved from GPIOA0 to GPIO92.
- EC_I2C_GYRO_SCL/SDA and EC_I2C_POWER_SCL/SDA were swapped.

BUG=chrome-os-partner:53791
BRANCH=none
TEST=Motion sensors work now.
