When an exact clock match is found, there is no need to continue
searching. This process was optimized for versal as part of
'commit e0a94c6bb5b4 ("clk: xilinx: Optimize divisor search in
clk_wzrd_get_divisors_ver()")' but that logic wasn't applied to
the non-versal driver.
Apply this fast-exit logic to the non-versal driver.
