We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/armada/armada_gem.c:215:27: warning: no previous prototype for 'armada_gem_alloc_object' [-Wmissing-prototypes]
drivers/gpu/drm/armada/armada_gem.c:423:1: warning: no previous prototype for 'armada_gem_prime_map_dma_buf' [-Wmissing-prototypes]
In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.
