Subject: [PATCH v3 09/11] ARM: dts: imx6ul-kontron-n6x1x-s: Disable the
 snvs-poweroff driver

From: Frieder Schrempf <frieder.schrempf@...tron.de>

The snvs-poweroff driver can power off the system by pulling the
PMIC_ON_REQ signal low, to let the PMIC disable the power.
The Kontron SoMs do not have this signal connected, so let's remove
the node.

This seems to fix a real issue when the signal is asserted at
poweroff, but not actually causing the power to turn off. It was
observed, that in this case the system would not shut down properly.

Signed-off-by: Frieder Schrempf <frieder.schrempf@...tron.de>
