Add Rotation setting to Framebuffer
Add a Rotation setting to the Framebuffer type that tells us if the
framebuffer is rotated by 90, 180 or 270 degrees. The hardware should
rotate the picture in the opposite direction before display.
To support more complex memory layouts, we also add a V_Stride (ver-
tical stride) setting.
