drm/msm/dpu: Remove suspend state tracking from crtc
Since drm core's modeset locks serialize atomic commits, we don't need to
track whether or not we're in a suspended state from inside the crtc for
dpu_crtc_enable/disable. This patch removes the suspend logic from the crtc and
removes the relevant tracing from dpu_trace. Since we removed all calls
to dpu_kms_is_suspend_state, we can remove that function and the
suspend_state field of dpu_kms as well.
v2: added patch to patchset
v3: reworded commit body and moved deletion of dpu_kms_is_suspend_state and
suspend_state to this patch
