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.

v2: Use sizeof(*pointer) pattern (Jani).
