Whoa, hold on.

First of all when you have three copies of the the same thing in different
directories there's bound to be trouble.
For example the 8260 & 5xx copies are already slightly out of sync.

Secondly LEDs are board specific and not cpu specific.
It was a coincidence that up to now the LEDs happened to be in cpu ports
and could be groupped under the cpu directories.

I think it is trivial to abstract the led operations into their respective
cpu include files for the common case. The existing board config headers
shouldn't be modified, while allowing other boards to override them.

In this case the status led code would be generic for all configurations
that support them.
