[PATCH 3/4] ARM: dts: exynos: fix USB 3.0 pins supply being turned off on Odroid XU

[Krzysztof Kozlowski <krzk@kernel.org>]

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.
