drm/radeon/kms: add support for gui idle interrupts (v4)
Useful for certain power management operations. You
need to wait for the GUI engine (2D, 3D, CP, etc.) to be
idle before changing clocks or adjusting engine parameters.
(v2) Fix gui idle enable on pre-r6xx asics

workaround it in the driver.
(v4) Add support for evergreen
