ARM: dts: exynos: fix USB 3.0 pins supply being turned off on Odroid XU
commit bd7e7ff56feea7810df900fb09c9741d259861d9 upstream.
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.
