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
(v3) The gui idle interrrupt status bit is permanently asserted
on pre-r6xx chips, but the interrrupt is still generated.
workaround it in the driver.
(v4) Add support for evergreen
