Title: tests: remove need for pow,log2 in hwtimer_wait

Default to precalculated value for geometric series, so pow and log2 are not needed.

The problem is that for `arduino-mega2560` the math functions were undefined.
Apart from that it does not really make sense to calculate this principally static value.
