soc: hisilicon: Support HCCS driver on Kunpeng SoC 



The Huawei Cache Coherence System (HCCS) is a multi-chip interconnection
bus protocol. This driver is aimed to support some features about HCCS on
Kunpeng SoC, like, querying the health status of HCCS.

This patch adds the probing of HCCS driver, and obtains all HCCS port
information by the dimension of chip and die on platform.

	  The Huawei Cache Coherence System (HCCS) is a multi-chip









	  interconnection bus protocol.









	  The performance of application may be affected if some HCCS









	  ports are not in full lane status, have a large number of CRC









	  errors and so on.



















	  Say M here if you want to include support for querying the









	  health status and port information of HCCS on Kunpeng SoC.
