This cleans up the hibernation Kconfig and removes the need to
declare centrally which architectures support hibernation. All
architectures that currently support hibernation are modified
accordingly.

Architecture maintainers should evaluate whether their
ARCH_SUSPEND_POSSIBLE symbol should be set only under
stricter circumstances like I've done for powerpc.

Always setting it is not usually a problem, however, since the
infrastructure is only available for use after suspend_set_ops().
