mx53loco: Allow to print CPU information at a later stage

Print CPU information within board_late_init().

This is in preparation for adding 1GHz support, which requires programming a PMIC
via I2C. As I2C is only available after relocation, print the CPU information
later at board_late_init(), so that the CPU frequency can be printed correctly.
