[ Upstream commit 80e993988b97fe794f3ec2be6db05fe30f9353c3 ]
This one nukes all framebuffers, which is a bit much. In reality gma500 is igpu and never shipped with anything discrete, so there should not be any difference.
v2: Unfortunately the framebuffer sits outside of the pci bars for gma500, and so only using the pci helpers won't be enough. Otoh if we only use non-pci helper, then we don't get the vga handling, and subsequent refactoring to untangle these special cases won't work.
It's not pretty, but the simplest fix (since gma500 really is the only quirky pci driver like this we have) is to just have both calls.
v4: - fix Daniel's S-o-b address
v5: - add back an S-o-b tag with Daniel's Intel address
