Shaveta Leekha 5e5097c110 board/b4860qds: Add support to make Aurora work on B4860QDS 
1) Add new SerDes1 protocols having Aurora in them
2) Add VSC cross point connections for Aurora to work with
   CPRI and SGMIIs
3) Configure VSC crossbar switch to connect SerDes1
   lanes to aurora on board, by checking SerDes1 protocols
4) SerDes1 Refclks have been set properly to make
   Aurora, CPRI and SGMIIs to work together properly
