Obvious good point instead to tell DSP BIOS which timers to use as part 
of the params we pass to the DSP similar to what we do with frequencies 
for DSP Load balancer to work.. makes it scalable and does not allow DSP 
to hog a timer which could be used for LCD backlight dimming with PWM 
for example..
