dt-bindings: net: dp83822: support configuring RMII master/slave mode
Add property ti,rmii-mode to support selecting the RMII operation mode
between:
- master mode (PHY operates from a 25MHz clock reference)
- slave mode (PHY operates from a 50MHz clock reference)
If not set, the operation mode is configured by hardware straps.
