Register with the USB OTG core. Since we don't support
OTG yet we just work as a dual-role device even
if device tree says otg.
Use extcon framework to get VBUS/ID cable events and
kick the OTG state machine.

The OTG core will use struct otg_hcd_ops to
add/remove the HCD controller.
The main purpose of this interface is to avoid directly
calling usb_add/remove_hcd() from the OTG core as they
wouldn't be defined in the built-in symbol table if
CONFIG_USB is m.

in dwc3_otg_init() but dwc3_otg_irq() has
already saved OEVTEN as 0 into dwc-oevten. So finally when
dwc3_irq_thread_irq() is called we save 0 into OEVTEN
thus disabling OTG irqs forever.
We fix this by disabling IRQs when configuring OEVTEN in
dwc3_otg_init().
