clk: imx: fracn-gppll: fix the rate table
The Fvco should be range 2.4GHz to 5GHz, the original table voilate the
spec, so update the table to fix it.
Fixes: c196175acdd3 ("clk: imx: clk-fracn-gppll: Add more freq config for video pll")
Fixes: 044034efbeea ("clk: imx: clk-fracn-gppll: fix mfd value")
Fixes: 1b26cb8a77a4 ("clk: imx: support fracn gppll")
