ARC: export clear_user_page() for modules
0day bot reports a build error:
ERROR: modpost: "clear_user_page" [drivers/media/v4l2-core/videobuf-dma-sg.ko] undefined!
so export it in arch/arc/ to fix the build error.
In most ARCHes, clear_user_page() is a macro. OTOH, in a few
ARCHes it is a function and needs to be exported.
PowerPC exported it in 2004. It looks like nds32 and nios2
still need to have it exported.
Fixes: 4102b53392d63 ("ARC: [mm] Aliasing VIPT dcache support 2/4")
