Update the ps_to_freq function to use a range of values instead of expecting an exact value. Adjust the 2133 and 1866 values to be larger than the expected JEDEC value by 1 in order to handle possible rounding issues with the SPD data.

This cahnge was tested with the M393A1G40DB0-CPB RAM module which
was rejected by the previous code due to the time_in_ps being 938
instead of the previously expected value of 937.

Memtester was run with the resulting configuration and shows no errors:
