After kernel commit:
http://git.yoctoproject.org/cgit/cgit.cgi/linux-yocto-3.0/commit/?h=meta&id=9728c1b6a724daefc413b44e10253cdbb5e06d08
It appears that the emulated colours in qemu are incorrect and that
the red and blue channels are reversed. This patch reverses that logic
so the colours are correctly displayed on the versatile platform which
doesn't support the BGR bit.
