drm/amdgpu: Split amdgpu_device_fini into early and late
Some of the stuff in amdgpu_device_fini such as HW interrupts disable and pending fences finilization must be done right away on pci_remove while most of the stuff which relates to finilizing and releasing driver data structures can be kept until drm_driver.release hook is called, i.e. when the last device reference is dropped. v4: Change functions prefix early->hw and late->sw Signed-off-by: Andrey Grodzovsky <andrey.grodzovsky@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210512142648.666476-3-andrey.grodzovsky@amd.com
