clk: imx-imx8mp: Mark arm_a53_core clk as critical
Changes in imx8mp.dtsi for v5.8-rc1 added some clock reparenting to the
device tree. IMX8MP_CLK_A53_CORE is reparented to IMX8MP_ARM_PLL_OUT.
The latter is not enabled in hardware, so the CPU clock is disabled
locking up the system. Mark IMX8MP_CLK_A53_CORE as critical so that the
new parent gets enabled before reparenting.
Fixes: abef60363d ("dts: update to v5.8-rc1")
