Subject: [PATCH RESEND v3 0/2] soc: hisilicon: Support HCCS driver on Kunpeng SoC

This series add HCCS driver to query the health status and port information
of HCCS on Kunpeng SoC as well as document all sysfs entries provided by
this driver.

---
 v3:
  - replace "using_status" with "enable" attribute.
  - fix some comments in codes.

 v2:
  - Document all sysfs entries provided by driver.
  - drop 'pcc_type' and 'intr_mode' in struct hccs_dev.
  - using _CRS with PCC GAS to get channel ID instead of _DSD.
  - replace readw_relaxed_poll_timeout with readw_poll_timeout.
  - use sysfs_emit() instead of sprintf().
  - drop ACPI_PTR in hccs_driver.
  - drop useless log during the probe phase.
