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.

Currently, there is an error when the i.MX93 CPU frequency is
read:
Could not read CPU frequency: -2
CPU: NXP i.MX93(52) Rev1.1 A55 at 0 MHz
Fix it by describing the A55 clock nodes in the devicetree, like done
on other i.MX SoCs.
With this change, the CPU frequency error is gone and it can be
