ARM: dts: exynos: fix USB 3.0 pins supply being turned off on Odroid XU
On Odroid XU LDO12 and LDO15 supplies the power to USB 3.0 blocks but the GPK GPIO pins are supplied by LDO7 (VDDQ_LCD). LDO7 also supplies GPJ GPIO pins. The Exynos pinctrl driver does not take any supplies, so to have entire GPIO block always available, make the regulator always on.
