Add missing header for HTC Dream framebuffer

Add missing header for HTC Dream framebuffer

[Dmitri Vorobiev]

Hi Pavel,

I'm wondering what happened to the patch [1] that added
include/linux/msm_mdp.h? I would be very interested in having this
header at where it belongs, and think that since the merge window is
open now, it would be good time to get back to that patch. :)

Thanks,
Dmitri

I hope it is in akpm tree somewhere. If it is not there in -rc1 we can
retransmit it.

Just checkrd -rc1, and the file is still not there. Looks like it's
time to retransmit it.

Thanks,

This should fix compilation by adding missing include/linux/msm_mdp.h
file.
