Changes in v2:
- Remove 0x from fdt aliases
- Use "okay" instead of "ok" for fdt node status
Changes in v3:
- Disable USB2 which is not used on Seaboard
- Fix device tree indenting with tabs instead of spaces
- Remove "okay" from nodes since this is the default anyway
Changes in v5:
- Remove support-host-mode property
Changes in v6:
- Remove dr_mode properties from SOC .dtsi file and move to boards
