[PATCH] ARM: dts: omap4-droid4: Configure EHCI so modems can be accessed

[Tony Lindgren <tony-4v6yS6AI5VpBDgjK7y7TUQ@public.gmane.org>]

Droid 4 has two modems, mdm6600 and w3glte. Both are on the HCI USB
controller.

Let's add a configuration for the HCI so the modems can be enabled.

Note that the modems still need GPIO based configuration that can
be done with the test-d4-echi shell script I've posted to:
