Hi - I have found a bug in the ARCH=powerpc Walnut BSP.  The order of 
the ethernet interrupts in the walnut.dts file doesn't match the 
documentation.  I discovered this when porting the BSP to a custom board 
- the ethernet would not work.  The attached patch corrects that.

This is the first patch I am submitting, so please advise me if there is 
anything I should do differently.
