tegra: correct gpio_index_to_port() calculation
The gpio_index_to_port() incorrectly was dividing by GPIO_PORTS_PER_BANK on a value including the bit number. After masking off the BANK offset just divide by the number of gpios in a port to get the port offset. BUG=chrome-os-partner:29981 BRANCH=None TEST=Built and ran through to depthcharge. Printed bank, port, and bit numbers for validation.
