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

From: Alex Deucher <alexander.deucher@xxxxxxx>

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)
