drm/rockchip: drop use of drmP.h

Drop use of the deprecated drmP.h header file.

While touching the list of include files move the
blocks so they follow the common pattern:

\#include <linux/*>

\#include <video/*>

\#include <drm/*>

\#include ""

Within each block sort the include files.
Add the includes needed to fix build after the removal of drmP.h.
