xf86-video-sunffb fix

[Mark Kettenis]

The following diff is necessary to compile the sunffb on OpenBSD.

ffb_asm.s: Assembler messages:
ffb_asm.s:67: Error: detected global register use not covered by .register pseudo-op

NetBSD has similar changes in, and frankly speaking, I would be
surprised if the Linux distros that care about SPARC don't have
something similar.

Can somebody commit this?
