Subject: [PATCH] dt-bindings: nfc: marvell,nci: fix reset line polarity in
 examples

The reset line is supposed to be "active low" (it even says so in the
description), but examples incorrectly show it as "active high"
(likely because original examples use 0 which is technically "active
high" but in practice often "don't care" if the driver is using legacy
gpio API, as this one does).
