ARM: s3c: Drop config symbol S3C24XX_PWM

The only effect of this symbol is to select PWM_SAMSUNG. Drop it and fix
the affected defconfigs to still keep PWM_SAMSUNG=y. Developers using
MACH_NEO1973_GTA02 and/or MACH_RX1950 now have to manually select PWM and
PWM_SAMSUNG (and get the freedom to select is as a module or not at all).
A side effect of this change is that allmodconfig now contains
PWM_SAMSUNG=m (which was =y before).
