drm/amdgpu: register a dirty framebuffer callback for fbcon

fbcon requires that we implement &drm_framebuffer_funcs.dirty.
Otherwise, the framebuffer might take a while to flush (which would
manifest as noticeable lag). However, we can't enable this callback for
non-fbcon cases since it may cause too many atomic commits to be made at
once. So, implement amdgpu_dirtyfb() and only enable it for fbcon
framebuffers (we can use the "struct drm_file file" parameter in the
callback to check for this since it is only NULL when called by fbcon,
at least in the mainline kernel) on devices that support atomic KMS.

drm/amdgpu: Retry DDC probing on DVI on failure if we got an HPD interrupt

HPD signals on DVI ports can be fired off before the pins required for
DDC probing actually make contact, due to the pins for HPD making
contact first. This results in a HPD signal being asserted but DDC
probing failing, resulting in hotplugging occasionally failing.

Rescheduling the hotplug work for a second when we run into an HPD
signal with a failing DDC probe usually gives enough time for the rest
of the connector's pins to make contact, and fixes this issue.
