Thank you for your reminder, actually I waited an answer on this nice subject: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-September/368643.html
But this is not relevant for this change anyway, if we should set a pull-(up|down) on all push-pull pads to reduce power consumption it should be enforced in the pinctrl driver, the dt must stay logical.
I just sent a v2 with all useless comments removed as suggested by Alexandre and without the explanation about the removed extra power consumption when removing a pull-(up|down) on a push-pull output because it does even seem to be the contrary on Atmel SoCs.
