fb: mmp: include linux/platform_device.h

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.

removed an implicit inclusion of linux/platform_device.h
In a number of places. This adds back explicit inclusions in a few
more places I found.

This file isn't my tty tree, so I can't apply that part of the patch,
but I've applied the rest of the patch, and the 2 others you sent me to
fix this issue.

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