arm: omap5: dts: add palmas-usb node

Without this node, there will be no palmas driver to notify dwc3 that a cable has been connected and, without that, dwc3 will never initialize.

---

after this, all we need is wait EXTCON merge which contains the final changes necessary to get USB3 working out of the box.

I'd suggest waiting on this patch until EXTCON reaches mainline, just to make sure we don't end up with DTS data for devices which don't exist.

cheers

1.8.2.1

this is not entirely correct. v3.11-rc1 has almost everything we need, already have a newer version of this patch but dwc3 has decided not to behave.

don't apply this version
