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.

       If present, select the RMII operation mode. Two modes are
       available:
         - RMII master, where the PHY operates from a 25MHz clock reference,
         provided by a crystal or a CMOS-level oscillator
         - RMII slave, where the PHY operates from a 50MHz clock reference,
         provided by a CMOS-level oscillator
       The RMII operation mode can also be configured by its straps.
       If the strap pin is not set correctly or not set at all, then this can be
       used to configure it.
