Commit "98e0500eadb7 media: i2c: imx290: Add configurable link frequency and pixel rate" then doubled the link frequency when in 2 lane mode, but didn't undo the correction for running at only 30fps, just extending horizontal blanking instead. Remove the 30fps limit on 2 lane by correcting the register config in accordance with the datasheet for 60fps operation over 2 lanes.
