Commit 60e93575476f (serial: samsung: enable clock before clearing pending interrupts during init) added handling of the controller clock during init. On most systems this clock is also one of the baud_clock sources and possibly used by the earlycon and thus already enabled by the bootloader. Therefore a gap exists between s3c24xx_serial_init_port disabling the clock and an attached console reenabling it, making the transition from earlycon to regular console possibly hang the system - as seen on my S3C2442 based Freerunner today. Therefore move the disabling of the clock from s3c24xx_serial_init_port below the uart port registration, effectively creating an overlap and keeping the clock running non-stop if the console wants to grab this port.
