[PATCH 2/4] dt-bindings: power: supply: add max77759-fg flavor and don't require nvme address

From: Thomas Antoine <t.antoine@uclouvain.be>

As the Maxim max77759 fuel gauge has no non-volatile memory slave address,
make it non-obligatory. Except for this, the max77759 seems to behave the
same as the max1720x.
