ARM: dts: enable USB functionality for exynos4210-universal_c210
This patch adds device tree nodes necessary to enable USB support on
universalc210 board, this includes UDC controller (USB gadget) as well
as EHCI and OHCI host ports. LDO3 and LDO8 regulators are switched to
always on mode until EHCI and OHCI drivers will support them correctly.
