Add 16GT/s specific equalization and rx lane margining settings. These settings are inline with respective PHY settings for 16GT/s 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.
v2 -> v3: - Replaced FIELD_GET/FIELD_PREP macros for bit operations. - Renamed cmn to common. - Avoided unnecessary argument validations. - Addressed review comments from Konrad and Mani.
v1 -> v2: - Capitilized commit message to be inline with history - Dropped stubs from header file. - Moved Designware specific register offsets and masks to pcie-designware.h header file. - Applied settings based on bus data rate rather than link generation. - Addressed review comments from Bjorn and Frank.
