[v2] arm64: dts: meson: odroid-n2: extend cpu opp-points

[Tim Lewis]

Odroid N2 has a large heatsink and HardKernel supports overclock
through the addition to extra opp points in their official kernel
sources [1]. Add these to the N2 dts only, as other S922X devices
may not have suitable heatsinks.
