Subject: ARM: dts: exynos: fix USB 3.0 pins supply being turned off on Odroid
 XU
Git-commit: bd7e7ff56feea7810df900fb09c9741d259861d9
Patch-mainline: v5.11-rc1
References: git-fixes

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.
