Implement DESY's RTM D1.3 pinout
To allow the board to be used with a wider array of RTMs, it is necessary to try to follow the industry standard.
From Tomazs suggestion:
Missing LVDS lines can be muxed with the HA/HB lines of one of the FMCs
using a passive multiplexer. The RTM will still need
the same Vadj as the mezzanine, though...
