This also caches the TSEG region and therefore increases MTRR usage a
little in some cases.

8M was set in the assumption that at least 4M was needed for IED
(Intel Enhanced Debug) , but this is not true.
The SMRR MTRR's need to have TSEG aligned to its size which is easier when TSEG
is only 2M. Also at most 6M of RAM more becomes available for use.

Having cbmem floating between two ram regions is a bad idea and some

pci ops happen to work on this struct device since the device_path is an union.
This patch still keeps adding the fixed resources in the pci_domain
ops since moving it to the PCI ops which could properly use the

Provide all gfx init methods as a Kconfig `choice`. This elimates the
option to select native gfx init along with running a Video BIOS. It's
been only theoretically useful in one corner case: Hybrid graphics
where only one controller is supported by native gfx init. Though I
suppose in that case it's fair to assume that one would use SeaBIOS to
run the VBIOS.
For the case that we want the payload to initialize graphics or no
pre-boot graphics at all, the new symbol NO_GFX_INIT was added to the
choice. If multiple options are available, the default is chosen as
follows:
* NO_GFX_INIT, if we add a Video BIOS and the payload is SeaBIOS,
* VGA_ROM_RUN, if we add a Video BIOS and the payload is not SeaBIOS,
* NATIVE_VGA_INIT, if we don't add a Video BIOS.
As a side effect, libgfxinit is now an independent choice.
