The Cypress CY7C6563x is a 2/4-port USB 2.0 hub. Add support for this hub in the driver in order to bring up reset, supply or clock dependencies. There is no reset pulse width given in the datasheet so we expect a minimal value of 1us to be enough. This hasn't been tested though due to lack of hardware which has the reset connected to a GPIO.
