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. This may support for reducing system power
consumption if there are HCCS ports supported low power feature
on platform.

Say M here if you want to include support for querying the
health status and port information of HCCS, or reducing system
power consumption on Kunpeng SoC.
