Allow topology to specify formatted strings so machine board's
predefined ->link_mask can be used to specify SSP port number
automatically.

This is done to help reduce the amount of topology files as many I2S
configurations contain codec of the same type with little to no
differences in number of scenarios supported - the only difference being
the port number codec is connected to.
