Your path looks fine to me. But it looks like those HSMC_CLK_OUT outputs take a straight shot to the HSMC connector. Do you have anything plugged into the HSMC slot that terminates the clocks? LVDS doesn't work very well when not terminated.

If you can't terminate the clocks then try a single-ended output standard, such as LVCMOS. LVCMOS should be able to run at 50MHz no problem.
