drm/amd/powerplay: add the smu manager for vega20 (v2)

The SMU manager handles the driver interaction with the SMU
which handles clock and voltage controls.

v2: switch to SOC15 register access macros
    reserve space for ActivityMonitor table
    enable SMU fw loading
    Drop dead code from bringup
