[PATCH 1/6] dt-bindings: ti, sci: Add property for partial-io-wakeup-sources

[Markus Schneider-Pargmann <msp@baylibre.com>]

Add a property with an array of phandles to devices that have pins that
are capable to wakeup the SoC from Partial-IO. In Partial-IO everything
is powered off including the DDR. Only pins belonging to a couple of
devices are active and wakeup the system on activity.
