Subject: [PATCH v2] [media] s5p-fimc: Only build suspend/resume for PM

From: Thierry Reding <treding@...dia.com>

If power management is disabled these functions become unused, so there
is no reason to build them. This fixes a couple of build warnings when
PM(_SLEEP,_RUNTIME) is not enabled.

Signed-off-by: Thierry Reding <treding@...dia.com>
