usb: dwc3: core: add dt support for dwc3 core
Added dt support for dwc3 core and update the documentation with device tree binding information. Getting a PHY is now done using devm_usb_get_phy_by_phandle() for dt boot. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
