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.
