usb: misc: onboard_hub: add support for Microchip USB2412 USB 2.0 hub

Browse Source 
[ Upstream commit e59e38158c61162f2e8beb4620df21a1585117df ]

The USB2412 is a 2-Port USB 2.0 hub controller that provides a reset pin
and a single 3v3 powre source, which makes it suitable to be controlled
by the onboard_hub driver.

This hub has the same reset timings as USB2514/2517 and the same
onboard hub specific-data can be reused for USB2412.
