At the request of Arnd Bergmann this patch moves all SoC
platform devices found in sysfs from /sys/devices/platform to
/sys/devices/soc/<SoCNum>_<SocMachine>/. It is believed as the
devices are SoC specific and a /sys/devices/soc node has recently
become available, that this would be a more appropriate place to
display the data.
