Mikita Lipski e5b03032e3 drm/amdgpu - Disable all irqs before disabling all CRTCs 
By moving amdgpu_irq_disable_all earlier in the sequence
fixes an issue with disabling pflip interrupts:

*ERROR* dal_irq_service_dummy_ack: called for non-implemented irq source

Earlier patch fixed a memory corruption and revealed irq
warnings.This way it seems to be there no obvious issues
with unloading the module.

Michel Dänzer a3f73c8cf4 drm/radeon: Don't turn off DP sink when disconnected 
Turning off the sink in this case causes various issues, because
userspace expects it to stay on until it turns it off explicitly.

Instead, turn the sink off and back on when a display is connected
again. This dance seems necessary for link training to work correctly.
