Subject: [PATCH 4.14 115/178] ARM64: dts: meson-gxbb-odroidc2: fix usb1 power supply

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Neil Armstrong <narmstrong@...libre.com>


[ Upstream commit e841ec956e539f4002f5e9fe9f9e904dcca12d5d ]

Looking at the schematics, the USB Power Supply is shared between the
two USB interfaces,
If the usb0 fails to initialize, the second one won't have power.
