The Integrator has a custom <mach/memory.h> header defining the BUS_OFFSET for *_to_bus and bus_to_* operations as offset from 0x80000000. This switches the Integrator over to using the mechanism introduced for the Keystone to provide the same offset using the device tree, deletes <mach/memory.h> and augments the Integrator device tree to provide the bus offset.
