Support new version of DDRC/SLLC PMU identified with updated ACPI HID and
register definition. 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 opertaions (by MN PMU).

Change since v1:
- Fold patch which extending the struct hisi_pmu_dev_info into its user
- Use bit shift rather than bit mask for SLLC PMU registers configuration
- Address other comments by Jonathan, thanks
