[PATCH v4 1/3] dt-bindings: mfd: twl: enable power button also for twl603x

From: Andreas Kemnade <andreas@kemnade.info>

TWL603x has also a power button function, so add the corresponding subnode.
As not in all cases there is a power button connected to the corresponding
pad of the TWL603x, the functionality can be disabled by
status = "disabled" or simply not adding the subnode.
To keep things simple, follow the established design pattern of using const
interrupts as used also by the other subdevices.
