usb: misc: onboard_usb_hub: Add support for Cypress CY7C6563x
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.
