Subject: [Patchv2] arm64: dts: meson-g12b-odroid-n2: add 5v regulator gpio

As described in the Odroid-n2 & Odroid-n2-plus schematics,
the 5V regulator is controlled by GPIOH_8 and in Open Drain
since this GPIO doesn't support Push-Pull.

Fixes: c35f6dc5c377 ("arm64: dts: meson: Add minimal support for Odroid-N2")
Fixes: ef599f5f3e10 ("arm64: dts: meson: convert ODROID-N2 to dtsi")
