[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.
