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.

The databook clearly states that the MSI IRQ (msi_ctrl_int) is a level
triggered interrupt.
The msi_ctrl_int will be high for as long as any MSI status bit is set,
thus the IRQ type should be set to IRQ_TYPE_LEVEL_HIGH, causing the
IRQ handler to keep getting called, as long as any MSI status bit is set.
A git grep shows that ipq4019 is the only SoC using snps,dw-pcie that has
configured this IRQ incorrectly.
Not having the correct IRQ type defined will cause us to lose interrupts,
which in turn causes timeouts in the PCIe endpoint drivers.

Improve the DTS files by removing all the leading "0x" and zeros to fix
the following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
and
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +
For simplicity, two sed expressions were used to solve each warnings
separately.
To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before
the opening curly brace:
https://elinux.org/Device_Tree_Linux#Linux_conventions
