To make the ethernet cable plugin detection reliable the
power detection of the smsc phy has been disabled.

The i2c bus can freeze at the end of transaction so the bus can no longer work.
This scenario is improved by adding scl/sda gpios definitions to implement the
i2c bus recovery mechanism.

Add aliases for i2c and serial to match the order of the DHCOM
standard [1]. Also add aliases for the two rtcs. The i2c rtc
is the primary one.

Add VIO regulator that supplies multiple ethernet magnetics and
currently there is no upstream support for that in the networking,
so just keep the regulator enabled always to emulate what other
boards, which have this hard-wired, do. Until there is support.

Enable the interrupt mode for the ethernet PHY by adding the
necessary property and a separate pinctrl for the PHY. Also
add the compatible property for it.

Fill in the custom GPIO line names used by DH on the DHCOM SoM.
The GPIO line names are in accordance to DHCOM Design Guide R04
available at [1], section 3.9 GPIO. Adding also GPIO line names
for the hardware and memory coding.

The pin CSI0_DATA_EN is reserved for PCIe Wake. Move this pin to
the SoM devicetree. Add PCIe Reset GPIO to the board devicetree.

Set stdout-path to "serial0:15200n8" to align it with other DHCOM
SoMs like the DHCOM STM32MP1.

On the PDK2 there are 4 keys and 4 leds. DHCOM GPIOs are
used for that, but one led isn't useable, because the GPIO
is already use as touch interrupt.

The PDK2 board is capable of running both 100M and 1G ethernet. However,
the i.MX6 has only one ethernet MAC, so it is possible to configure
either 100M or 1G Ethernet. In case of 100M option, the PHY is on the
SoM and the signals are routed to a RJ45 socket. For 1G the PHY is on
the PDK2 board with another RJ45 socket. 100M and 1G ethernet use
different signal pins from the i.MX6, but share the MDIO bus.
This SoM board combination is used to demonstrate how to enable 1G
ethernet configuration.

Define each DHCOM GPIO as a separate pinctrl. So on board layer it is
possible to easily add an used DHCOM GPIO by moving &pinctrl_dhcom_X
from the gpio hog list to the appropriate driver pinctrl.

The minimum available memory size of all DHCOM i.MX6 variants is 512 MB.
Set this value for the memory node. If U-Boot fails to fill the memory
size, at least all DHCOM i.MX6 variants should run without problems.

Following cleanups of the devicetrees done, no change in function:
- Remove parentheses from the license
- Update copyright date
- Alphabetical sorting
- Add comments
- Update pinctrl names
- Hex values in lower case
- Replace interrupt type with a define

The DH electronics PDK2 can be populated with SoM with i.MX6S/DL/D/Q
variants. Split the SoC-independent parts of the SoM and PDK2 into the
imx6qdl-dhcom-*.dtsi and reduce imx6q-dhcom-dpk2.dts to example of
adding i.MX6S/DL/D/Q variants of the SoM into a PDK2 carrier board.

Add DT for DH DRC02 unit, which is a universal controller device.
The system has two ethernet ports, two CANs, RS485 and RS232, USB,
capacitive buttons and an OLED display.
