We can add a new c-state to let system suspend enter into the same deep
state as s2ram when using s2idle, but we don't want other cases to use
that c-state, such as play_idle() which would find the deepest state by
invoking find_deepest_state() as well. This patch-set provides users
an option which can restrict c-state to be found as deepest state for
s2idle only.

  cpuidle: allow idle state to be found as deepest state for s2idle only
  dt-bindings: arm: Add description to the new property for-s2idle-only
