[POWERPC] OProfile: fix cbe pm signal routing problem

Browse Source 
Fix debug_bus_control and group_control PMU register values set up in
set_pm_event().  Initialize variables before calling set_pm_event().
Delete unused static array and code that initialized it.
Rename constant to better reflect usage.
