[PATCH] arm64: dts: rk3399: Remove extcon unit address and extcon-cells from Gru

[Enric Balletbo i Serra]

The cros-ec-extcon has no reg property so remove the unit address from
the DT node to make DT compiler happy.

While here, remove the inexistent extcon-cells property from the extcon
nodes.

Thanks to the Dafna's work and Rob's review I got noticed that the old
txt binding was wrong, and also, that the current cros-ec-extcon node in
Gru is wrong, so sending this patch now that is fresh in our minds and
update the node accordingly. There is an extcon-cells property that seems
to not exist and is not documented, so remove it.

For reference, see https://lkml.org/lkml/2020/2/5/176.
