Because there are multiple variants to the stmmac/dwmac driver, the
dts bindings should be updated to include version of the IP used.

 * STMicroelectronics 10/100/1000 Ethernet driver (GMAC)
 
 Required properties:
-- compatible: Should be "st,spear600-gmac"
+- compatible: Should be "snps,dwmac-<ip_version>" "snps,dwmac"
+        For backwards compatibility: "st,spear600-gmac" is also supported.
 - reg: Address and length of the register set for the device
 - interrupt-parent: Should be the phandle for the interrupt controller
   that services interrupts for this device
