CPU's idle states are defined by the arm,idle-state compatible flag. See
[1]. PM domains that can contains devices and other domains also has
similar definition for its idle state. Reuse the definition of
arm,idle-state for PM domains by allowing an addition compatible string
("domain-idle-state") to denote idle states that are specific to PM
