[U-Boot] [PATCH 6/7 v2] OMAP3: Add OMAP3 core changes for MUSB

[Dirk Behme]

OMAP3 core changes necessary for MUSB

Signed-off-by: Dirk Behme <dirk.behme at googlemail.com>

---
Note: OMAP3 USB code will be sent later to USB maintainer, so
      CONFIG_MUSB isn't used anywhere yet. This will avoid
      USB maintainer to change OMAP3 core files.
