My H700 (RG35XX-H, RG40XX-V and RG CubeXX) devices are very unstable,
especially with some OPPs.
Crashes were fairly easy to reproduce with any dynamic cpufreq governor
and some load on CPU, usually in matter of minutes.
Crashes manifested randomly as simply hanging or various kernel oops

Manufacturer (Anbernic) is using more conservative mircrovolt values,
so let's use these.
While using performance gov seems stables at 1.5Ghz, it still crashes
using a dynamic gov (even with Andre reparenting patch), so let's drop
it for now, like manufacturer does.
