Subject: drm/amdgpu: Avoid leaking PM domain on driver unbind (v2)

From: Alex Deucher <[email protected]>

commit 458d876eb869d5a88b53074c6c271b8b9adc0f07 upstream.

We only support vga_switcheroo and runtime pm on PX/HG systems so forcing runpm to 1 doesn't do anything useful anyway.

Only call vga_switcheroo_init_domain_pm_ops() for PX/HG so that the cleanup path is correct as well. This mirrors what radeon does as well.

v2: rework the patch originally sent by Lukas (Alex)
