Hi!

This patch changes /sys/power/state to not advertise any valid states
(except for disk if SOFTWARE_SUSPEND is enabled) when no pm_ops have been
set so userspace can easily discover what states should be available.

Also, because the pm ops in powermac are obviously not using them as
intended, I added documentation for it in kernel-doc format.

Reordering the fields in struct pm_ops not only makes the output of
kernel-doc make more sense but also removes a hole from the structure on
64-bit platforms.

Looks okay to me.
