clk: imx: pll14xx: explicitly return lowest rate

clk_pll14xx_round_rate() returns the lowest rate by indexing into
the rate table with the variable i. i is actually pll->rate_count
as this is the value we come out of the loop with. Use pll->rate_count
explicitly to make it a bit more clear what is being done. While at
it fix a typo in the comment. No functional change.
