In this series, replace the original vmsvga driver to Bochs
interface.
Simply revert vmsvga driver implementation. After it, use Bochs
interface for initializing vmsvga.
Because of the PCI BARs difference between std vga and vmsvga.
We can not simply recognize the "QEMU VMWare SVGA" as the
QEMU_VIDEO_BOCHS_MMIO variant.
BAR | std vga | vmsvga
---------------------------------
0 | Framebuffer | I/O space
1 | Reserved | Framebuffer
2 | MMIO | FIFO
To overcome this problem, we remain variant QEMU_VIDEO_VMWARE_SVGA,
and use it for:
(1) Get framebuffer from correct PCI BAR
(2) Prevent using BAR2 for MMIO
We have tested on qemu before and after commit 104bd1dc70 and all
worked.

Changelog:
v1 -> v2
* use 'else' clause (Thanks Philippe).
* add more comment in revert patches (Thanks Philippe).
* reorder the revert patches, we should revert the last commit first.
* use correct framebuffer to ClearScreen.
* revert VMWare svga definitions.

Patch 5 (not yet merged) is still on my TODO because I want to run
