I cross-checked a few macros visually (not each one) and it LGTM in
terms of just moving it from dpu_formats.c to mdp_format.c
Even in this change I had the same concern about whether to use MDP for
dpu formats.
But I think even if we make it MSM_*** then we will have to keep them in
some msm_** header and not mdp_format.c
So lets go ahead with the MDP naming which you have. If we see its not
working out later on, please be open to a mass renaming that time.

I am now thinking that do you think it makes sense to move all
MDP_FORMAT macros to a new mdp_formats.h including the RGB/YUV bitfield
macros (even though I already acked that change).
Instead of bloating msm_drv.h even more?
