Agreed and fixed for V5.

The reason why they are defined this way is that they are for 
identifying the real device/revision on which you are running u-boot, as 
opposed to the intended device/revision for which you built it; they are 
only useful for parts of the code which are common to all orion5x 
variants (such as print_cpuinfo). Variant-specific code would not need 
it as it knows already which variant it is for.
