soundwire: cadence: split access to IP_MCP_CONTROL fields

The latest Cadence IP splits the MCP_CONTROL fields in two registers:
MCP_CONTROL and IP_MCP_CONTROL. Rename the relevant fields and change
the access methods used for those fields.

For existing solutions, this is an iso-functionality change.
