drm/amd/powerplay: add hardware manager sub-component
The hwmgr handles all hardware related calls, including clock/power
gating control, DPM, read and parse PPTable, etc.
v5: squash in fixes
v4: implement acpi's atcs function use cgs interface
v3: fix code style error and add big-endian mode support.
v2: use cgs interface directly in hwmgr sub-module
