    drm/i915: remove intel_uncore_clear_errors

Description:
------------------------
After the machine boot up with DP monitor, I pulled out the DP monitor's plug.Then I see there is Calltrace displayed on the monitor.
You can check the Calltrace in the attachment.

When I trace back to the drm-intel-next-queued kernel of June, the Calltrace are still reproducable. It's hard to find a good point. If need bisect, ping me. 

Reproduce steps:
----------------
1.Plug in DP monitor
2.Boot up the computer
3.Unplug the DP monitor
