Series clk: imx8m: Define gates for pll1/2 dividers | expand

Commit Message

On imx8mn there are 9 fixed-factor dividers for SYS_PLL1 and SYS_PLL2
each with their own gate. Only one of these gates (the one "dividing" by
one) is currently defined and it's incorrectly set as the parent of all
the fixed-factor dividers.

Add the other 8 gates to the clock tree between sys_pll1/2_bypass and
the fixed dividers.
