dt/bindings: remove device_type "network" references

device_type is deprecated and the kernel doesn't require it in most
cases. The only exceptions for flat tree users are the "gianfar",
"ucc_geth" and "ibm,emac" bindings, and arguably that requirement could
be relaxed for ucc_geth and ibm,emac (that is a task for separate
patches though).

This patch removes references to device_type="network" from the binding
documentation where possible and removes the properties from ARM and
microblaze dts files. This patch does not modify the powerpc .dts files
since there are a much larger number of them affected and I think the
ucc_geth, ibm,emac and gianfar users should be addressed before clearing
out the references to reduce the chance of breakage.

    Ethernet port node
 
    Required properties:
-     - device_type : Should be "network".
      - compatible : Should be "marvell,mv64360-eth".
      - reg : Should be <0>, <1>, or <2>, according to which registers
        within the silicon block the device uses.

    Example Discovery Ethernet port node:
      ethernet@0 {
-	     device_type = "network";
 	     compatible = "marvell,mv64360-eth";
 	     reg = <0>;
 	     interrupts = <32>;
