In order to support this, we do a preliminary refactor to initialize device of each version by using driver data of each HID rather than checking the version. This will also make the driver easier to maintain and extend, since only the HID specific information along with the new HID will be added to support the new version without touching the common logic. Two new Uncore PMU drivers is also added to support the monitoring the events of the system bus (by NoC PMU) and the DVM operations (by MN PMU). Change since v2: - Rebase on 6.15-rc1, add Jonathan's tag.
