Fix compilation error when CONFIG_CPU_FREQ_S3C24XX_DEBUGFS selected.

Signed-off-by: Denis Kuzmenko <linux@solonet.org.ua>
---

Patch is against 3.2-rc3.
CONFIG_S3C2410_IOTIMING wasn't present in Kconfig but was referenced by
Makefile. Because of this the file s3c2410-iotiming.c was not ever compiled
and enabling CONFIG_CPU_FREQ_S3C24XX_DEBUGFS option caused undefined
reference to function s3c2410_iotiming_debugfs defined in that file.
