[media] coda: fix build error by making reset control optional
make reset control optional for i.MX27 The patch "[media] coda: add reset control support" introduced a build failure if CONFIG_RESET_CONTROLLER is disabled: drivers/media/platform/coda.c:3734:2: error: implicit declaration of function 'devm_reset_control_get' Since not all SoCs containing CODA VPUs do have a system reset controller, use devm_reset_control_get_optional to make it optional.
