media: i2c: imx290: Use CSI timings as per datasheet

Commit "98e0500e 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.
