It's standard that we suffix all framebuffer drivers with an 'fb'. I'm
making it so in my tree.

Also, you shouldn't place your driver after vfb, that's why there's a
comment that the test framebuffer is last. If someone accidentally
enables vfb, he/she will get a blank screen. So I'm moving it under the
platform driver section.
