soundwire: stream: fix programming slave ports for non-continous port maps
Two bitmasks in 'struct sdw_slave_prop' - 'source_ports' and
'sink_ports' - define which ports to program in
sdw_program_slave_port_params(). The masks are used to get the
appropriate data port properties ('struct sdw_get_slave_dpn_prop') from
an array.
Bitmasks can be non-continuous or can start from index different than 0,
thus when looking for matching port property for given port, we must
iterate over mask bits, not from 0 up to number of ports.
This fixes allocation and programming slave ports, when a source or sink
masks start from further index.
