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

+ - 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,

+ 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.
