[RFC PATCH 4/7] ARM: s3c64xx: Fix build error with CONFIG_S3C_DEV_FB disabled

If there is no board selecting CONFIG_S3C_DEV_FB enabled, build will fail on
arch/arm/mach-s3c64xx/pm.c, where s3c_device_fb is referenced.

This patch adds ifdef guard around the code making it compile only when
CONFIG_S3C_DEV_FB is enabled.
