drm/kms/fb: use slow work mechanism for normal hotplug also.
a) slow work is always used now for any fbcon hotplug, as its not a fast task and is more suited to being ran under slow work. b) attempt to not do any fbdev changes when X is running as we'll just mess it up. This hooks set_par to hopefully do the changes once X hands control to fbdev. This also adds the nouveau/intel hotplug support. Signed-off-by: Dave Airlie <airlied@redhat.com>
