vga: Expose framebuffer byteorder as a QOM property
The VGA device model now supports having the framebuffer in either endian, and can be switched between these by the guest via a register in the qext region. However, in some cases (e.g. LE OS on the pseries machine) we have existing guest that don't know about the endian switch register, but other parts of the qemu code have better information to set a default endianness than the VGA code does of itself. In order to allow them to set a correct default endianness in these cases, without breaking abstraction walls, this patch exposes the VGA framebuffer endianness via a writable QOM property.
