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.
