[SPARC64]: In sunsu driver, make sure to fully init chip for kbd/ms
We were forgetting to call sunsu_change_speed(). The reason that replugging in the mouse cable "fixes things" is that causes a BREAK interrupt which in turn caused a call to sunsu_change_speed() which would get the chip setup properly. Signed-off-by: David S. Miller <davem@davemloft.net>
