Subject: usb: misc: onboard-hub: add support for Microchip USB5744

From: Stefan Eichenberger <stefan.eichenberger@xxxxxxxxxxx>

commit 6972b38ca05235f6142715db7062ecc87a422e22 upstream.

Add support for the Microchip USB5744 USB3.0 and USB2.0 Hub.

The Microchip USB5744 supports two power supplies, one for 1V2 and one
for 3V3. According to the datasheet there is no need for a delay between
power on and reset, so this value is set to 0.
