media: i2c: imx290: Use CSI timings as per datasheet
Commit "98e0500eadb7 media: i2c: imx290: Add configurable link frequency and pixel rate" added support for the increased link frequencies on 2 data lanes, but didn't update the CSI timing registers in accordance with the datasheet. Use the specified settings.
