[PATCH 02/21] ARM: s3c: remove s3c24xx specific hacks

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

A number of device drivers reference CONFIG_ARM_S3C24XX_CPUFREQ or
similar symbols that are no longer available with the platform gone,
though the drivers themselves are still used on newer platforms,
so remove these hacks.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
