This reverts commit c137d95081.
The VMWare SVGA model now -- since commit 104bd1dc70 in QEMU --
falls back to stdvga (that is, Bochs) if we don't setup VMWare SVGA
FIFO.
To simplify QemuVideoDxe, we don't intend to implement the VMWare SVGA
FIFO setup feature. It means our current VMW SVGA driver code is
basically dead. To simplify the problem, we will replace the old
VMWare SVGA driver to Bochs interface. It should work on all QEMU
version.
The first step for using Bochs interface is to revert old driver.
