Since commit d2d0ad2aec ("i2c: imx: use open drain for recovery
GPIO") GPIO lib expects this GPIO to be configured as open drain.
Make sure we define this GPIO as open drain in the device tree.
This gets rid of the following warning:
gpio-81 (scl): enforced open drain please flag it properly in DT/ACPI DSDT/board file
Note that currently the i.MX pinctrl driver does not support
enabling open drain directly, so this patch has no effect in
practice. Open drain is enabled by the fixed pinmux entry.

Boards based on imx6qdl have duplicate memory nodes:
- One coming from the board device tree file: memory@
- One coming from the imx6qdl.dtsi file.
Fix the duplication by removing the memory node from
the imx6qdl.dtsi file and by adding 'device_type = "memory";'
in the board Device Tree.
Converted using the following command:
perl -p0777i -e 's/memory\@10000000 \{\n/memory\@10000000 \{\n\t\tdevice_type = \"memory\";\n/m' `find ./arch/arm/boot/dts -name "imx6*"``

The pinctrl properties on the IOMUXC node get overwritten by the
carrier board level device tree, hence the pinctrl_reset_moci
pinctrl does not get applied.
Associate the pinctrl_reset_moci pinctrl with the PCIe node where
we also make use of the pin as a reset GPIO.
Since the pin is muxed as a GPIO by default not muxing it explicitly
worked fine in practise.

Remove the 2.5V regulator, it does not exist. There is 3.3V and
3.3V_AUDIO provided to the module through the edge connector,
model those as fixed regulators like we use to do in other
Colibri device trees. The SGTL5000 uses 3.3V_AUDIO as VDDA. Note
that the driver derives the analog ground voltage (VAG) from this
supply. The new value should allow higher output swings before
clipping occurs. Refer to the SGTL5000 datasheet for details.
