soundwire: cadence: change access to IP_MCP_CMD_BASE
The latest Cadence IP moves MCP_CMD_BASE and MCP_CMD_RESP to the
IP_MCP_CMD_BASE and IP_MCP_CMD_RESP registers located in different
area and accessed with a fixed offset.
Unlike other patches, the fields are not renamed to avoid a very
invasive and low-value set of changes.
For existing solutions, this is an iso-functionality change.
