[POWERPC] spufs: Use separate timer for /proc/spu_loadavg calculation
The original spusched_timer was designed to take effect only when
a context is waiting in the runqueue.
This change adds an additional lower-freq timer has been added to
purely handle the spu_load updates. The new timer will be triggered
per LOAD_FREQ ticks.
