drm/amdgpu: partially revert powerplay __counted_by changes

Partially revert
commit 0ca9f757a0e2 ("drm/amd/pm: powerplay: Add `__counted_by` attribute for flexible arrays")

The count attribute for these arrays does not get set until
after the arrays are allocated and populated leading to false
UBSAN warnings.
