[POWERPC] cell: add support for registering sysfs attributes to spus
In order to add sysfs attributes to all spu's, there is a need for a list of all available spu's. Adding the device_node makes also sense, as it is needed for proper register access. This patch also adds two functions to create and remove sysfs attributes and attribute_groups to all spus. That allows to group spu attributes in a subdirectory like: /sys/devices/system/spu/spuX/group_name/what_ever This will be used by cbe_thermal to group all attributes dealing with thermal support in one directory.
