Subject: [PATCH net-next v3 1/2] dt-bindings: dp83867: Convert fifo-depth to common fifo-depth and make optional
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.

v3 - No changes
v2 - Rebase on linux-net next as the patch would not apply
