[PATCH 4.2.y-ckt 59/98] drm/amdgpu/pm: update current crtc info after setting the powerstate

[Kamal Mostafa]

4.2.8-ckt6 -stable review patch.  If anyone has any objections, please let me know.

From: Alex Deucher <alexander.deucher@xxxxxxx>

commit eda1d1cf8d18383f19cd2b752f786120efa4768f upstream.

On CI, we need to see if the number of crtcs changes to determine
whether or not we need to upload the mclk table again.  In practice
we don't currently upload the mclk table again after the initial load.
The only reason you would would be to add new states, e.g., for
arbitrary mclk setting which is not currently supported.
