usb: onboard-hub: Add reset-gpio support

As part of the reset, sets the direction of the pin to output before
toggling the pin. Delay of millisecond is added in between low and
high to meet the setup and hold time requirement of the reset.
Update the usb2514 hub_data with the reset delay and power on
delay values.
