Currently IGPs are left without DMA32 but we might need to change

The line mux for the connector in the bios tables
is used for enumerating drm connectors. Since
this laptop has a quirk where the same line much is
listed for both VGA and LVDS, the connectors get
combined. Setting the line mux on LVDS to an unused
value prevents both encoders from being combined into
the same connector. This should fix bko bug 13720.

Userspace sends us a special relocation type to sync video/exa
to vlines to avoid tearing, this deals with the relocation
in the kernel, it picks the correct crtc and avoids issues
where crtcs are disabled.

trying to do anything evil.

Normally we are free to place VRAM where we want in the GPUs
memory address space, however on IGP chips the VRAM is actual RAM,
and no special translation or aperture is used inside the GPU MC.
So when you move the VRAM aperture away from the TOM register,
you actually move it into main memory and can trash things quite badly.
This commit makes the code respect the TOM location for MC_FB_LOCATION.
