Arnd Bergmann 18a9927878 ARM: ux500: move soc_id driver to drivers/soc ... As the ux500 id code is basically a standalone driver, we can move it out of the arch code into drivers/soc/ux500. This is a user-visible change, as it moves all the devices in sysfs from /sys/devices/soc0/ to /sys/devices/ and leaves the soc0 node as a separate device. Originally the idea was to put all on-chip devices under the soc node, and ux500 was the first platform to have this device, but later platforms almost all didn't follow that pattern, so this makes the platform do the same thing as everyone else. Since the platform is really obsolete now, I am optimistic that nothing will break after moving the devices around. As the SoC driver no longer has access to the private header files, I'm changing the code to instead look up the address of the backupram from devicetree, which is a good idea anyway. Finally, having a separate Kconfig symbol means the driver is now optional and could even be a loadable module rather than always being built-in if we allowed that for soc_device.
