arch/sparc: Implement <asm/fb.h> with generic helpers

Replace sparc64's fb_pgprotect() with the generic one
from <asm-generic/fb.h>. On sparc, pgprot_writecombine() and
pgprot_noncached() are the same; hence no functional changes

v3:
* use default implementation for fb_pgprotect() on
  sparc64 (Arnd)
v2:
* restore the original fb_pgprotect()
