tty: serial: remove obsolete config SERIAL_SAMSUNG_UARTS_4
Commit
1ea35b355722 ("ARM: s3c: remove s3c24xx specific hacks"), allows
simplifying the whole config logic for SERIAL_SAMSUNG_UARTS, and did this
config simplification. However, it misses that SERIAL_SAMSUNG_UARTS_4's
effect was just to control SERIAL_SAMSUNG_UARTS, and with the commit's
change, the config SERIAL_SAMSUNG_UARTS_4 has no remaining effect and can
be deleted.
Remove this obsolete config SERIAL_SAMSUNG_UARTS_4.
