tests: Add configuration for small frequency dividers for system clock

Browse source 
For systems that have both high base (CPU, bus, etc.) frequency and
small divider of the base frequency for system clock and this way,
do not allow 1 second period for the system clock, set the system
clock period to 0.1.
