drm/amdgpu: move kfd_resume before the ip late init
The kfd_resume needs to touch GC registers to enable the interrupts,
it needs to be done before GFXOFF is enabled to ensure that the GFX is
not off and GC registers can be touched. So move kfd_resume before the
amdgpu_device_ip_late_init which enables the CGPG/GFXOFF.
