On the odroid N2 plus, cpufreq is not available due to an error on the cpu
regulators. vddcpu a and b get the same PWM. The one provided to vddcpu A
is incorrect. Because vddcpu B PWM is busy the regulator cannot register:
> pwm-regulator regulator-vddcpu-b: Failed to get PWM: -16
Like on the odroid n2, use PWM A out of GPIOE_2 for vddcpu A to fix the
problem

HardKernel ODROID-N2+ uses an Amlogic S922X rev. C chip capable of higher
clock speeds than the original ODROID-N2.
The rev. C support a slighly higher VDDCPU_A & VDDCPU_B voltages and supports
the same OPPs as the Amlogic A311D SoC from the same G12B family.
