ARM: integrator: hook the AP into the SoC bus
This hooks the Integrator/AP into the SoC bus when booting from device tree, by mapping the AP controller registers first, then registering the SoC device, and then populating the device tree with the SoC device as parent. Introduce some helpers in the core to provide sysfs files detailing the use of the SoC ID which will later be reused by the Integrator/CP patch for the same bus grouping.
