[PATCH 3/3] arm64: dts: meson: add support for the ODROID-N2+

[Christian Hewitt]

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.
