When would you ever not turn this on?
We don't want PHYS_64BIT on unconditionally. It has the effect of moving all the devices into high physical memory, which means you need a different Linux/dts. I expect the normal case to be that it is off. Just those few customers that actually want to do this will use the PHYS_64BIT version.
