dt-bindings: media: nxp,imx-mipi-csi2: Mark clock-frequency as deprecated

Usage of the clock-frequency property, which is already optional, is
discouraged in favour of using assigned-clock-rates (and
assigned-clock-parents where needed). Mark the property as deprecated,
and update the examples accordingly.
