kconfig: mention 'hibernation' not just swsusp
Clarify that "software suspend" is what's called "hibernation" in most user
interfaces, shrinking a terminology gap. (Examples include Gnome and
MS-Windows.)
Also provide a more succinct description of what it does, so you won't have
to read the whole novel in Kconfig; and highlights just why the lack of
BIOS requirements for swsusp are a big deal.
