Therefore, certain functions like RESET are exposed through the common registers of HNS module which are memory-mapped by the HNS driver and currently can only be accessed through DT/syscon interface. This patch adds the support of the RoCE Reset functionality through ACPI interface. This functionality would be exposed to the HiSilicon HNS Driver using the _DSM() ACPI Method. This method shall be called by the wrapper API in HNS driver. Further, HiSilicon RoCE driver shall call the HNS Driver exported RoCE Reset API. In this patch, DSDT ACPI Table have been amended to facilitate such support.
