This series mainly contains the refactor of the HiSilicon Uncore PMU by
extracting the common parts from each drivers into the core:
- the retrieving of the PMU topology ID
- the common sysfs attributes like cpumask and identifier

In order to achieve this, we need to do below preparation:
- improve the detection of associated CPUs for PMUs locates on a SICL
- maintain the topology information in a dedicated data structure

Besides also include below changes/cleanups in this patchset
- add one new sysfs attributes for better describing the topology information
  of the associated CPUs of the PMU.
- define a symbol namespace for HiSilicon Uncore PMUs to avoid pollute the
  common ones
- two minor nonfunctional cleanups of DDRC PMU

  drivers/perf: hisi: Fix incorrect variable name "hha_pmu" in DDRC PMU
    driver
  drivers/perf: hisi: Delete redundant blank line of DDRC PMU

Yicong Yang (6):
  drivers/perf: hisi: Define a symbol namespace for HiSilicon Uncore
    PMUs
  drivers/perf: hisi: Improve the detection of associated CPUs
  drivers/perf: hisi: Extract topology information to a separate
    structure
  drivers/perf: hisi: Add a common function to retrieve topology from
    firmware
  drivers/perf: hisi: Refactor the attributes creation
  drivers/perf: hisi: Export associated CPUs of each PMU through sysfs
