usb: misc: onboard_usb_hub: Add support for Cypress CY7C6563x

JIRA: https://issues.redhat.com/browse/RHEL-21064

commit 24af68a
Author: Frieder Schrempf <frieder.schrempf@kontron.de>
Date: Mon, 27 Nov 2023 12:22:26 +0100

    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.
