drm/armada: Replace drm_framebuffer_reference/unreference() with _get/put()

This patch replace instances of drm_framebuffer_reference/unreference with
*_get/put() suffixes, because get/put is shorter and consistent with the
kernel use of *_get/put suffixes.
This was done with the following Coccinelle script:

@r1@
expression e;
@@

(
-drm_framebuffer_reference(e);
+drm_framebuffer_get(e);
|
-drm_framebuffer_unreference(e);
+drm_framebuffer_put(e);
)
