clk: fractional-divider: tests: Add test suite for edge cases
In light of the recent discovery that the fractional divisor
approximation does not utilize the full available range for clocks that
are flagged CLK_FRAC_DIVIDER_ZERO_BASED [1], implement tests for the
edge cases of this clock type.

includes, store parent rate to compare instead of repeating equation]
