Timer code was written based on integer multiple HF clock frequencies. EFR32 doesn't conform to that (38.4), and so the timestamp ticks were off by 1%. Enough to trip up some CI tests on TB_SENSE_12 (ARMmbed#5496)

Description
The us_timer code was written based on MHz integer multiple HF clock frequencies, in order to optimize away some long division instructions. EFR32 doesn't conform to that (38.4), and so the timestamp ticks were off by 1%. Enough to trip up some CI tests on TB_SENSE_12 (resolves #5496)
