[PATCH 35/49] gma500: begin the config based split

[Alan Cox]

From: Alan Cox <alan@xxxxxxxxxxxxxxx>

We don't want to carry all the extra gunk around on every device so use the
splitting work so far to tidy this up. Poulsbo is still mandatory as it is
used in bits by the other drivers and not neatly modularised.
