drm/i915: add i915_ips_status debugfs entry
Description:
---------------------
When I start glxgears on our new IVB platform(Apple MacBook Pro), glxgears will
take a little more time to be activated. The graphics box will be black for a
while, then glxgears also worked properly. I checked the dmesg, there's some
error messages like below:
[ 461.016229] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU
hung
[ 461.016240] [drm] capturing error event; look for more information in
/sys/kernel/debug/dri/0/i915_error_state
[ 461.019565] [drm:i915_error_work_func], resetting chip
I also test other one IVB desktop platform, there's not this problem.
Reproduce steps:
---------------------
1. reboot machine
2. xinit &
3. glxgears &
4. checkout dmesg</pre>
