[PATCH V4 00/10] PCI/VGA: Rework default VGA device selection

[Huacai Chen]

My original work is at [1].

Bjorn do some rework and extension in V2. It moves the VGA arbiter to
the PCI subsystem, fixes a few nits, and breaks a few pieces to make
the main patch a little smaller.

V3 rewrite the commit log of the last patch (which is also summarized
by Bjorn).

V4 split the last patch to two steps.

All comments welcome!
