Faster image load from host to IT8951 Image Buffer #11

After a quick profile to see why I'm not achieving a 450ms full refresh (7.5s instead) with the example code for a Raspberry Pi, it appears that most of the wall clock time is being spent loading the image from the host to the IT8951 driver (IT8951HostAreaPackedPixelWrite()). Is there a way to accelerate this?
