fsl/pm: add api to get suspend state which is STANDBY or MEM
Add set_pm_suspend_state & pm_suspend_state functions to set/get
suspend state. When system going to sleep or deep sleep, devices
can get the system suspend state(STANDBY/MEM) through pm_suspend_state
function and to handle different situations.
