From: Daniel Vetter <daniel.vetter@ffwll.ch>
Only really pci devices have a business setting this - it's for
figuring out whether the legacy vga stuff should be nuked too. And
with the preceding two patches those are all using the pci version of
this.
Which means for all other callers primary == false and we can remove
it now.
v2:
- Reorder to avoid compile fail (Thomas)
- Include gma500, which retained it's called to the non-pci version.
v4:
- fix Daniel's S-o-b address

From: Daniel Vetter <daniel.vetter@ffwll.ch>
With the preceding patches it's become defunct. Also I'm about to add
a different boolean argument, so it's better to keep the confusion
down to the absolute minimum.
v2: Since the hypervfb patch got droppped (it's only a pci device for
gen1 vm, not for gen2) there is one leftover user in an actual driver
left to touch.
v4:
- fixes to commit message
- fix Daniel's S-o-b address
