net: dsa: qca8k: Add QCA8334 binding documentation 



commit 218bbea11a777c156eb7bcbdc72867b32ae10985 upstream.

Add support for the four-port variant of the Qualcomm QCA833x switch.

The CPU port default link settings can be reconfigured using
a fixed-link sub-node.

A CPU port node has the following optional node:

For QCA8K the 'fixed-link' sub-node supports only the following properties:



- 'speed' (integer, mandatory), to indicate the link speed. Accepted

  values are 10, 100 and 1000

- 'full-duplex' (boolean, optional), to indicate that full duplex is

  used. When absent, half duplex is assumed.
