ASoC: codecs: wcd939x: Move max port number defines to enum

Instead of having separate define to indicate number of TX and RX
Soundwire ports, move it to the enums defining actual port
indices/values.  This makes it more obvious why such value was chosen as
number of TX/RX ports.
Note: the enums start from 1, thus number of ports equals to the last
vaue in the enum.
