Add reset-gpios and reset-duration-us properties to the marvell,mv64xxx-i2c binding. These can be used to describe hardware where a common reset GPIO is connected to all downstream devices on and I2C bus. This reset will be asserted then released before the downstream devices on the bus are probed.
