ocfb: fix tgdel and tvdel timing parameters 

According to the ocfb documentation:
Fix tgdel HW param should be left margin, not right.
Fix tvdel HW param should upper margin, not lower.

This seems to fix lock issues on certain monitors (tested on a
slightly customized IP, but the FPGA guy said that it should
be the same wrt this changes).
