vga-pci: add qext region to mmio
Add a qemu extented register range to the standard vga mmio bar.
Right nowe there are two registers: One readonly register returning the
size of the region (so we can easily add more registers there if needed)
and one endian control register, so guests (especially ppc) can flip
the framebuffer endianness as they need it.
