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.
