For maintaining consistency with kernel coding style replace
reference/unreference in ref counting functions with get/put.

The following cocci script was used to generate the tilcdc patch:

@@
expression ex;
@@

(
-drm_framebuffer_unreference(ex);
+drm_framebuffer_put(ex);
|
-drm_dev_unref(ex);
+drm_dev_put(ex);
|
-drm_framebuffer_reference(ex);
+drm_framebuffer_get(ex);
)
