iBasso DX50/DX90: CPU info enhancements.

System -> Debug (Keep Out) -> View CPU stats

Will now show the current cpufreq scaling governor, minimum, current and
maximum cpufreq scaling frequency for each CPU.

This may be genric for Android kernel based devices but is only enabled
for iBasso Devices. Other maintainers may choose do adopt this.
