arm64: dts: mba93xxca: Do not assert power-down pins
Change the output to inactive (output-low) for active-low pins, resulting in high-voltage of power-down pins. Thus this enables the attached devices. Signed-off-by: Alexander Stein <alexander.stein@ew.tq-group.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
