arm64: dts: apq8096-db820c: Fix VDD core voltage
APQ8096 has its VDD APC (Power for quad Kryo applications microprocessors) powered by PM8996 PMIC S9, S10, S11 tri-phase regulators (gang). The bootloader may have configured these regulators with non sustainable default values, leading to sporadic hangs under CPU stress tests (cpufreq-bench). Ideally we should enable voltage scaling along with frequency scaling, but for now just set the regulator gang value to a sane voltage, capable of supporting highest frequencies (turbo).
