[PATCH v2 3/3] ARM: dts: omap: Add usb_otg and glue data

Add usb otg data node in omap4/omap3 device tree file. Also update
the node with board specific setting in omapx-<board>.dts file.
The dt data specifies among others the interface type (ULPI or UTMI), mode
which is mostly OTG, power that specifies the amount of power this can supply
when in host mode.
The information about this node is available @
Documentation/devicetree/bindings/usb/omap-usb.txt
