mmc: s3cmci: Register cpufreq notifier only on S3C24xx
The driver registered for CPU frequency transitions to recalculate its clock when ARM clock frequency changes (ratio between frequencies of ARM's parent clock (fclk) and clock for peripherals remains fixed). This is needed only on S3C24xx platform when cpufreq driver is enabled so limit the ifdef to respective cpufreq Kconfig.
