dt-bindings: dp83867: Convert fifo-depth to common fifo-depth and make optional

Browse Source 
Convert the ti,fifo-depth from a TI specific property to the common
tx-fifo-depth property.  Also add support for the rx-fifo-depth.

These are optional properties for this device and if these are not
available then the fifo depths are set to device default values.

- ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h

PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_TXID

Note: If the interface type is PHY_INTERFACE_MODE_RGMII the TX/RX clock delays
will be left at their default values, as set by the PHY's pin strapping.
