drm/fbdev: rework output polling to be back in the core. (v4)
After thinking it over a lot it made more sense for the core to deal with
the output polling especially so it can notify X.
v2: drop plans for fake connector - per Michel's comments - fix X patch sent to xorg-devel, add intel polled/hpd setting, add initial nouveau polled/hpd settings.
v3: add config lock take inside polling, add intel/nouveau poll init/fini calls
v4: config lock was a bit agressive, only needed around connector list reading.
otherwise it could re-enter.
glisse: discard drm_helper_hpd_irq_event
