OMAP4: PM: Program pwrst of each pwdm as per their supported state
Configure next power state of each power domain based on their
supported state. This will be done one time during initialization of
power_setup function. Device can change their power domain state runtime
based on dev latency requirement.
Also, this API will be called during suspend path as well to make sure each power
domain has been configured the right state before entering OFF transition.
