timer_irq: Increase maximum busy wait time to 2us
Increase the amount of time to "busy wait" in the timer dispatch loop
to 2 micro-seconds. This, in practice, causes stepper step and unstep
events to occur within a single hardware interrupt. Doing that helps
stabilize the single active stepper performance benchmarks.
