fb: mmp: include linux/platform_device.h

[Arnd Bergmann <arnd@arndb.de>]

Patch 16559ae "kgdb: remove #include <linux/serial_8250.h> from kgdb.h"
changes the kgdb.h file so that drivers including it do not implicitly
include linux/platform_device.h. The mmp framebuffer driver is new,
so Greg did not have a chance to fix it up when introducing his change.

Right. It seems the driver is only in Andrew's tree. Andrew, can you 
add this hunk on top?
