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:

 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.

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

 v2:
