Shreyas NC c91605f489 soundwire: Remove cdns_master_ops

Sanyog Kale 956baa1992 soundwire: cdns: Add sdw_master_ops and IO transfer support
Implement sdw_master_ops with support for xfer_msg, xfer_msg_defer
and reset_page_addr. Since Cadence module doesn't know the systems
it will be used, set the read_prop to the bus helper.
