Add the description for the USB OTG port.
The OTG port uses a dedicated regulator for vbus.

Add the description for the USB host port.
This port is linked to a resettable USB HUB so handle
this reset signal with a GPIO hog.

Add support of the lt8912b in the DTB.
This adds the support of the DB_DSIHD daugther board from
Boundary Devices.
