We set up two USB ports, one of which can be host or device.
For some reason the kernel version does enable both ports.

Changes in v2:
- Use "okay" instead of "ok" for fdt node status
- Remove 0x from fdt aliases
Changes in v3:
- Remove "okay" from nodes since this is the default anyway
- Fix device tree indenting with tabs instead of spaces
- Disable USB2 which is not used on Seaboard
