[PATCH v4 1/2] PM: suspend: Define pm_suspend_target_state

[Kai-Heng Feng]

Define pm_suspend_target_state so it can still be used when
CONFIG_SUSPEND is not set.

Signed-off-by: Kai-Heng Feng <kai.heng.feng@xxxxxxxxxxxxx>
---
v4:
 - Move pm_suspend_target_state to CONFIG_SUSPEND block.

v3:
 - New patch to resolve undefined pm_suspend_target_state.
