The following error and warnings will be seen when compiling a C file
which includes <drm/drm_gem_cma_helper.h> but without <drm/drmP.h>
being included before.

include/drm/drm_gem_cma_helper.h:5:24: error: field ‘base’ has incomplete type
include/drm/drm_gem_cma_helper.h: In function ‘to_drm_gem_cma_obj’:
include/drm/drm_gem_cma_helper.h:16:9: warning: initialization from incompatible pointer type [enabled by default]

include/drm/drm_gem_cma_helper.h:24:34: warning: its scope is only this definition or declaration, which is probably not what you want [enabled by default]

include/drm/drm_gem_cma_helper.h:46:14: warning: ‘struct drm_device’ declared inside parameter list [enabled by default]

Fix them by including <drm/drmP.h> in drm_gem_cma_helper.h.
