pipeline: rkisp1: Support devices without self path
Some hardware supported by the rkisp1 driver, such as the ISP in the
i.MX8MP, don't have a self path. Although at the moment the driver still
exposes the self path, prepare the rkisp1 pipeline handler for when the
self path will be removed for devices that don't support it.
