Do you need to define print_cpuinfo locally?

I know I did the same on mx53loco, and the reason is that due to the
PMIC I need to read the CPU frequency after the PMIC has raised the
core voltage and bumped to 1GHz.

I do not see PMIC definitions in this board, so you probably you can
just remove this local definition and add
#define CONFIG_DISPLAY_CPUINFO into your m53evk.h board instead.
