Because of props like:

       #cpus = <1>;
       #address-cells = <1>;
       #size-cells = <0>;

If these used some other symbol instead of '#' cpp will be happy and  
we can use it to create macros for us.

I think it will get really really confused if the dts says "$cpus = 1"
but that turns into a "#cpus" property.

There are other macro processors besides cpp, you know - why not look
at m4, for instance?
