drm/nouveau/core: rework event interface
This is a lot of prep-work for being able to send event notifications
back to userspace. Events now contain data, rather than a "something
just happened" signal.
Handler data is now embedded into a containing structure, rather than
being kmalloc()'d, and can optionally have the notify routine handled
in a workqueue.
Various races between suspend/unload with display HPD/DP IRQ handlers
automagically solved as a result.

drm/nouveau/disp/dp: maintain link in response to hpd signal
This previously worked for the most part due to userspace doing a
modeset in response to HPD interrupts. This will allow us to
properly handle cases where sync is lost for other reasons, or if
userspace isn't caring.
