video/aperture: Move vga handling to pci function

video/aperture: Move vga handling to pci function

[ Upstream commit f1d599d315fb7b7343cddaf365e671aaa8453aca ]

A few reasons for this:

- It's really the only one where this matters. I tried looking around,
  and I didn't find any non-pci vga-compatible controllers for x86
  (since that's the only platform where we had this until a few
  patches ago), where a driver participating in the aperture claim
  dance would interfere.

- I also don't expect that any future bus anytime soon will
  not just look like pci towards the OS, that's been the case for like
  25+ years by now for practically everything (even non non-x86).

- Also it's a bit funny if we have one part of the vga removal in the
  pci function, and the other in the generic one.

v2: Rebase.

v4:
- fix Daniel's S-o-b address

v5:
- add back an S-o-b tag with Daniel's Intel address
