#1219794 — [PATCH] [media] atmel-isi: Protect PM-only functions to kill warning

If CONFIG_PM=n:

    drivers/media/platform/soc_camera/atmel-isi.c:1044: warning: ‘atmel_isi_runtime_suspend’ defined but not used
    drivers/media/platform/soc_camera/atmel-isi.c:1054: warning: ‘atmel_isi_runtime_resume’ defined but not used

Protect the unused functions by #ifdef CONFIG_PM to fix this.
