Subject: [PATCH] ARM: SAMSUNG: Fix compilation error with s3c2410_defconfig

Commit 2663e766c56a ("ARM Samsung: Move s3c pwm driver to pwm framework")
moved Samsung PWM driver to drivers/pwm and the config option to select
this driver has changed.

This patch fixes following build-error with s3c2410_defconfig.
