adi_board.tcl: ad_xcvrcon: Add lane mapping support 

Add a parameter to the ad_xcvrcon function that allows to provide a mapping
between logical and physical lanes. By default if no lane map is provided
the logial and physical lanes are mapped 1-to-1. If a lane map is provided
logical lane $n is mapped onto physical lane $lane_map[$n].
