Subject[PATCH v3] 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.
