    CPU: Define a config variable for 64-bit address capability
    
    For the most part, we don't need 64-bit addressing. In the future,
    it will be more important, but it's useful to have an indicator
    that a CPU can even run in that mode.

+	  Many of the CPUs in our tree can support 64-bit addresses.
+	  Currently, we don't use this capability on any of them.
+	  This variable indicates whether it is even possible,
+	  for a given CPU, to run in 64-bit mode. For the subset of
+	  CPUs which can support 64-bit mode it can be overridden.
