Add Gen4 specific equalization and rx margining settings. These settings are inline with respective PHY settings for Gen4 operation. In addition, current QCOM EP and RC drivers do not share common codebase which would result in code duplication. Hence, adding common files for code reusability among RC and EP drivers.
