[SPARC64]: Fix two year old bug in early bootup asm.
We try to fetch the CIF entry pointer from %o4, but that can get clobbered by the early OBP calls. It is saved in %l7 already, so actually this "mov %o4, %l7" can just be completely removed with no other changes. Signed-off-by: David S. Miller <davem@davemloft.net>
