This series adds support to calculate system memdev parameters and calculate total system memory bandwidth. This parameters and BW will be used to enable WM level-0 latency workaround and display memory bandwidth related WA for gen9. while we are here to enable IPC based on memory configuration lets also make sure that we override IPC value set of BIOS incase we decide to disable IPC in KMS.
