[PATCH v3 6/9] ARM: dts: omap: dm816x: Update USB node

[Ettore Chimenti]

From: Andrew Goodbody <andrew.goodbody at linaro.org>

USB node was not working correctly with DMA enabled as the supporting
code had been updated without updating this SoC's device tree. Bring the
device tree more up to date so that it works with DMA enabled.
Removing deprecated usb_otg_hs `ti,hwmods` property in DT node in favour
of ti-sysc implementation.
