Why IMX93_CLK_ARM_PLL and not IMX93_CLK_A55_SEL ?
IMX93_CLK_A55_SEL is a mux that can select between a55_alt versus arm_pll.

IMX93_CLK_A55_SEL is a mux that can select between a55_alt versus arm_pll.
The real CPU clock is IMX93_CLK_

Fix it by describing the A55 clock nodes in the devicetree, like done
on other i.MX SoCs.
