This is some gradual improvements to the FOTG210 dual-mode USB host/gadget driver.
- Create stricter device tree bindings fixing some mistakes. We have at least FOTG200 and FOTG210 out there. A third variant named FUSB220 is probably related but has a separate driver in the vendor code trees.
- Start to break out common code for remapping of memory and clock handling to begin with, move this to the core file.
- Check that the block is in the right role before proceeding, don't abort registration but print a warning if it's not.
- Assing some default speed and the OF node when the UDC starts. This is based on the similar pattern in the DW controllers.
- Implement a proper VBUS session handler calling down to the hardware VBUS control handler in the Gemini variant. This makes everything work on my hardware.
