Add ODROID-N2+ support (#793)

Browse Source 
* Add ODROID-N2+ support

Add ODROID-N2+ support with the new SoC revision c. Extend the U-Boot
script: Assume ODROID-N2 if the SoC revision is "a" (there are only "a"
revision SoCs on ODROID N2) and assume N2+ otherwise.

Currently using overclock mode as proposed in the upstream kernel patches.

* Update hassos-hook.sh

Subject: [PATCH 10/10] arm64: dts: meson: add support for the ODROID-N2+
HardKernel ODROID-N2+ uses an Amlogic S922X rev. C chip capable of higher
clock speeds than the original ODROID-N2. Hardkernel supports the big cpu
cluster at 2.4GHz and the little cpu cluster at 2.0GHz. Opp points and
regulator changess are from the HardKernel Linux kernel sources.
