imx: imx8ulp: Clear dividers in PLL3DIV_PFD registers

At present, in cgc1_pll3_init we don't set the pll3pfd div values,
just use the default 0. But on A1 part, ROM will set PLL3 pfd1div2
to 1 and pfd2div1 to 3.
This finally causes some clocks' rate decreased, for example USDHC.
So clear the PLL3DIV_PFD dividers to get correct rate.
