For sh at least turning on CONFIG_PM without PM_SLEEP or PM_RUNTIME is
largely pointless, so the bulk of the defconfigs have it turned off. The
few platforms that do use CONFIG_PM for something also have more
comprehensive support implemented. The few times we do have it enabled
without one of the others supported is simply for build coverage, mostly
due to sharing drivers (whatever isn't already triggered through
rand/allyes/modconfigs).
I would expect that this is a common scenario for the bulk of the
defconfigs that reflect PM being a platform-specific vs architecture-wide
property regardless of architecture, however.
