Add the ability to register only one of the two possible
main framebuffer devices on the SM501 by passing platform
data for only the framebuffer that you are interested in
having.
As a side note, we update the init sequence to commonise
the code that is executed twice, and fix a pair of missing
frees that we didn't do on framebuffer exit, such as freeing
the fb's cmap.
