Subject: [PATCH net v3 4/5] dt: cpsw: phy-handle, phy_id, and fixed-link are mutually exclusive

From: David Rivshin <drivshin@...worx.com>

The phy-handle, phy_id, and fixed-link properties are mutually exclusive,
and only one need be specified. Make this clear in the binding doc.

Also mark the phy_id property as deprecated, as phy-handle should be
used instead.

 Note: "ti,hwmods" field is used to fetch the base address and irq
 resources from TI, omap hwmod data base during device registration.
 Future plan is to migrate hwmod data base contents into device tree
 blob so that, all the required data will be used from device tree dts
 file.
