drm/amd: Fix hybrid sleep

Browse source 
[Why]
commit 530694f54d ("drm/amdgpu: do not resume device in thaw for
normal hibernation") optimized the flow for systems that are going
into S4 where the power would be turned off.  Basically the thaw()
callback wouldn't resume the device if the hibernation image was
successfully created since the system would be powered off.

This however isn't the correct flow for a system entering into
s0i3 after the hibernation image is created.  Some of the amdgpu
callbacks have different behavior depending upon the intended
state of the suspend.

[How]
Use pm_hibernation_mode_is_suspend() as an input to decide whether
to run resume during thaw() callback.
