Only if the minimum interrupt latency is less than 1 decrementer
tick. That seems pretty unlikely to me unless you have a very slow
timebase frequency.
In fact what we should program the decrementer to is:
timeout - (is_booke? 0: 1) - min_interrupt_latency
I was assuming that min_interrupt_latency (measured in timebase ticks)
would be at least 1, but apparently some systems can have a timebase
frequency as low as 1kHz, so we'll have to have an ifdef or something.
