PM resume was crashing during dpu_kms_pm_resume. This patch removes
dpu_kms_pm_suspend/resume so that msm_pm_suspend/resume uses the atomic
helpers instead (see next patch). This patch also removes
dpu_kms_is_suspend_blocked since it is never called.
v2: Reorganized patches in patchset
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

msm_pm_suspend/resume since we just deleted those functions (see patch
1). Also removes the drm_kms_helper_poll_disable/enable calls, since
the DRM_CONNECTOR_POLL_CONNECT flag is never set so periodic polling
doesn't happen anyways.
v2:
Since we removed all suspend logic from the crtc code (see patch 3/4),
dpu_crtc_reset does the same things as drm_atomic_helper_crtc_reset, so let's
just replace it with a call to the atomic helper.

The CP performance counter selects were accidentally marked as protected
so they couldn't be written from PM4 streams. Remove the protection
because user space does have an interest in setting up their own
counters.

This can be rolled up into patch 3, since that's where the usage of these is
being removed.

dpu_crtc_enable/disable/reset are only being called upon
initialization/destruction of the device and as part of the PM

are guarenteed to not overlap with one another we don't need to
