Got it. I just found nokia-dsi-panel.h is some kind of confusing and
tried to unify them. Obviously I should not touch them in this
patchset. I will remove them in next version.

OK, I got it. Actually I did that, but wanna unify the
nokia-dis-panel.h somehow. I will change back.

Got it. I will fold some patches together.

I found this is common in all the generic dpi panel, but the value
depends on the specific panel. I move this to the panel configuration
data and will set this value in panel-dpi driver. Do you think need I
keep them here? Actually I found all of them are 24 for generic one.
16 or 18 for others.
