drm/rockchip: fix compile error when build as modules

Browse Source 
Build fail with:
  ERROR: "memblock_free" [drivers/gpu/drm/rockchip/rockchipdrm.ko] undefined!

memblok_free fuction not export symbol, and use the flag __init, so it
can't be used on modules.

the memblock_free function only used for loader memory manager, not use
on modules context, so just use it when build-in drm/rockchip.
