[V2,5/6] clk: imx8mn: Improve ARM PLL table to support CPU frequency scaling

Commit Message

Anson Huang Aug. 17, 2019, 10:28 p.m. UTC

i.MX8MN supports CPU running at 1.5GHz/1.4GHz/1.2GHz, add missing
frequency for ARM PLL table, also add .rate_count assignment which
is necessary for searching required PLL rate from the table.
