PATCH v3 1/1 arm64: dts: meson: S922X: extend cpu opp-points
HardKernel supports overclock through the addition to extra opp points in their official kernel sources for odroid-n2 [1]. Christian tested on other S922X devices with "no obvious issues". Neil thinks dvfs and thermal managementis can keep other S922X devices safe.

The patch is well formed but I can only test on Odroid-N2.
Anyway, Christian did a test other S922X boxes and it doesn't crash.

Oops, will fix in v4.
