[Intel-gfx] [PATCH 3/5] drm/i915: Ditch INTELFB_CONN_LIMIT

[Daniel Vetter]

And the gratious overallocation of crtcs. Seems to go back to the ums
days of yonder ...

We also still need it to make the fbdev emulation happy, but I don't
think there's really a need. Especially since the current fbdev
emulation doesn't actually support cloning.
