MIPS: Octeon: Add sched_clock() to csrc-octeon.c

Browse source

With the advent of function graph tracing on MIPS, Octeon needs a high
precision sched_clock() implementation.  Without it, most timing
numbers are reported as 0.000.

This new sched_clock just uses the 64-bit cycle counter appropriately
scaled.
