-Binding for Texas Instruments interface clock.

-This binding uses the common clock binding[1]. This clock is
-quite much similar to the basic gate-clock [2], however,

- "ti,omap3-no-wait-interface-clock" - interface clock which has no hardware

- "ti,omap3-hsotgusb-interface-clock" - interface clock with USB specific HW

Nice to see this! These are the top occurring undocumented (by schema)
warnings for arm32.
