soundwire: cadence: split access to IP_MCP_CMDCTRL fields
The latest Cadence IP splits the MCP_CMDCTRL fields in two registers:
MCP_CMDCTRL and IP_MCP_CMDCTRL. Rename the relevant fields and change
the access methods used for those fields.
In practice we only use the Parity error insertion in IP_CMD_CTRL.
For existing solutions, this is an iso-functionality change.
