============================================================================
This module deals with setting up SERDES configuration for HYPERLINK. The API flow should be as follows:
CSL_HyperlinkSerdesInit (base_addr, ref_clock, rate);
CSL_HyperlinkSerdesLaneConfig (base_addr, ref_clock, rate, lane_num);
CSL_HyperlinkSerdesComEnable (base_addr);
CSL_HyperlinkSerdesLaneEnable (base_addr, lane_num, link_rate, loopback_mode, lane_ctrl_rate);
CSL_HyperlinkSerdesPllEnable (base_addr);
CSL_HyperlinkSerdesGetStatus (base_addr, num_lanes);
OR
CSL_HyperlinkSerdesGetPLLStatus (base_addr);
CSL_HyperlinkSerdesGetLaneStatus (base_addr, lane_num); //Individual lane status
