drm/amdgpu: Fix selfring initialization sequence on soc24

Move enable_doorbell_selfring_aperture from common_hw_init
to common_late_init in soc24, otherwise selfring aperture is
initialized with an incorrect doorbell aperture base.

Port changes from this commit from soc21 to soc24:
commit 1c312e816c40 ("drm/amdgpu: Enable doorbell selfring after resize FB BAR")
