arch/sparc: Implement fb_is_primary_device() in source file
Other architectures implment fb_is_primary_device() in a source file. Do the same on sparc. No functional changes, but allows to remove several include statement from <asm/fb.h>. v2: * don't include <asm/prom.h> in header file Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: "David S.
