update diff, remove unnecessary code

At first look only:

- the '#ifndef MT7531' is clearly incompatible with GENERIC kernel.
the defined FDT bindings between the NIC and the switch are not followed. Instead, a "brutal" hack (fdt_find_ethernet_prop_switch) is used.
the eqos driver changes is improper. All of these are should be in attached the phy driver.

I also think this breaks eqos driver on other boards (without switch), but I'm not 100% sure. The diff doesn't contain context, so it's difficult to read it.
In any case, these three points must be solved first.

This revision now requires changes to proceed.Sun, Feb 1, 9:57 AM
