Subject: [PATCH v3 4/4] arm64: dts: exynos: gs101: enable ufs, phy on oriole & define ufs regulator

Enable ufs & ufs phy nodes for Oriole. Also define the ufs regulator node.

ufs regulator is a stub until full s2mpg11 slave pmic support is added.
The gpio defined is for the BOOTLD0 (gs101) signal connected to
UFS_EN(s2mpg11) gpio enabled voltage rail for UFS.
