iBasso DX50/DX90: User selectable freq scaling governor.

Depends on http://gerrit.rockbox.org/r/#/c/1043/.

This patch adds a new setting in Settings -> General
-> System: Freq Scaling Governor

Usable in Quickscreen and Shortcuts.

Possible settings are:
- Conservative: Slow frequency switching.
- Ondemand or Interactive: Fast frequency switching.
- Powersave: Allways lowest frequency.
- Performance: Allways highest frequency.

German translation provided.

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