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.

---
 v7:
 - split patch 1/2 to make it easier to review.                 
 - fix a wrong command code in hccs_get_die_all_link_status(). 
 - remove unused code and fix a log description in error branch.

 v6:
 - fix the new entry in MAINTAINERS file to keep alphabetical order

 v5:
 - fix document format to eliminate warning of making htmldocs.

 v4:
 - remove useless header and reorder linux header.
 - use __ATTR_RO to replace __ATTR for port attributes.
 - add MODULE_DEVICE_TABLE to autoload the driver.
 - update the date to "November 2023".
 - fix some comments about HCCS description.

 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.
