pmdomain: ti_sci: handle wakeup constraint for out-of-band wakeup
For devices capable of out-of-band system wakeups via I/O daisy chaining,
prevent sending wakeup constraints to the PM co-processor. This allows
the system to enter deeper low power modes, as the device is not marked
as requiring power.
Replaces the logic from commit b06bc4727991 ("pmdomain: ti_sci: handle
wake IRQs for IO daisy chain wakeups") since checking out-of-band wakeup
will cover the same functionality.
Detect out-of-band wakeup in the suspend path, and if it exists, skip
sending the constraint.
