Updated: Sys-clk-OC, Loader, System_settings

- Sys-clk-OC

  - Major cleanup in clock_manager, preparing to add basic Erista support.

  - Added an experimental CPU & GPU frequency governor.

    - Known issue:

      - Occasional stuttering is expected: GPU load% metric PMU_GET_GPU_LOAD does not reflect real utilization precisely. Use another metric, some interpolation algo or add min frequency option for improvement.

- Loader

  - Addressed an issue for Erista variants: Boot with unmodified Fusee or Hekate, nn::pcv::EmcDvfsPeriodicCompHandler will fail with rc 0x8C5. Fixed by removing 40.8 MHz while retaining 1600.0 MHz MEM table -- however, this means user has to use modified sys-clk.
