drm/sun4i: drop use of drmP.h

Drop use of the deprecated drmP.h header file.

While touching the list of include file, use the typical order of the
blocks:
\#include <linux/*>

\#include <video/*>

\#include <drm/*>

\#include ""

Within each block, sort the files.
Include necessary files to fix build after the drmP.h removal.
