Subject: [PATCH (2.6.25) 2/2] suspend: clean up Kconfig

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

Acked-by fest. I hope I didn't forget anyone.

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().
