[SPARC64]: Fix sched_clock() wrapping every ~17 seconds.
Unfortunately, sparc64 doesn't have an easy way to do a "64 X 64 -->
128" bit multiply like PowerPC and IA64 do. We were doing a
"64 X 64 --> 64" bit multiple which causes overflow very quickly with
a 30-bit quotient shift.
So use a quotientshift count of 10 instead of 30, just like x86 and
ARM do.
This also fixes the wrapping of printk timestamp values every ~17
seconds.
