Add a V4L2 meta format code (V4L2_META_FMT_QCOM_CAMSS_PARAMS) for the Qualcomm CAMSS ISP parameter buffer. This format is used by the params video node exposed by CAMSS offline ISP drivers (e.g. OPE) to carry per-frame ISP tuning data such as white balance, color correction and chroma enhancement settings.
