[POWERPC] cell: add temperature to SPU and CPU sysfs entries
This patch adds a module that registers sysfs attributes to CPU and SPU
containing the temperature of the CBE.
They can be found under
/sys/devices/system/spu/cpuX/thermal/temperature[0|1]
/sys/devices/system/spu/spuX/thermal/temperature
The temperature is read from the on-chip temperature sensors.
