media: imx-pxp: make data_path_ctrl0 platform dependent
Unfortunately, the PXP_HW_VERSION register reports the PXP on the i.MX7D and on the i.MX6ULL as version 3.0, although the PXP versions on these SoCs have significant differences. Use the compatible to configure the ctrl0 register as required dependent on the platform.
