  1. Increase cycle count for unoptimized cortex-m0 

    Cortex-M0 doesn't have 32bitx32bit=64bit multiplication instructions
and can not use SCURVE use optimized path.

Increasing to actual cycle count of 544 to hopefully improve
stability of board as well as a form of documentation that people
should consider disabling SCURVE feqature until the code is optimized
for cortex-m0;

Stepper::calc_timer_interval() use of division is also been identified
as taking 126 cycles.
