Add support for the SolidRun LX2160A Twins board in its single cpu
configuration.
The twins board is designed to host a pair of LX2160A CEX-7 modules,
sharing a single PCI-E connector in multi-host mode.
It may be assembled in two configurations (different assembly options
facilitating signal re-routing), with a single or with dual CEX-7
module. Their marketing names are:
- SolidWAN Single LX2160
- SolidWAN Dual LX2160
Add the single configuration, featuring:
- 8x SFP (1Gbps)
- 8x SFP+ (1/10Gbps)
- PCI-E OCP card connector
- USB-3.0 front-panel header with single port
- microSD
- dual hot-swappable power supplies

LX2160A CEX-7 module provides a total of 4 USB ports to the carrier
board, one from first usb controller, and 3 from a hub behind the second
controller.
Both controllers currently have their status set okay in the module's
dtsi file. However devices should be disabled by default when
incomplete.
The first USB controller is only completed by a carrier board featuring
a device or USB connector.
The second controller hosts a USB hub and should therefore be active.
Add description for the USB hub, and enable the first controller only in
the carrier board description.

Originally includes were defined hierarchically:
- CEX-7 Module includes SoC
- Clearfog-CX & Honeycomb common parts include CEX-7 Module
- Boards include common parts
This makes it difficult to modify the includes on a per-board level,
e.g. when adding a new board based on CEX-7 module but revision 2 SoC
(which now has its own soc dtsi).
Move includes of both SoC and CEX-7 module out of common parts and into
each board dts.

The SolidRun LX2160A Twins board supports two configurations, one with
with a single CEX-7 module, and one with two (dual).
The single configuration is a specific assembly that maximises
connectivity for single cpu by routing some second cpu resources to the
first via zero-Ohm resistors.
The dual configuration was not yet tested and is intentionally omitted.
Initial review strongly suggests that the dual configuration will have
different bindings, because from either cpu point of view the board
appears different (e.g. different number of sfp, fewer i2c gpio).
Add binding for the single variant only.

Fix the PCIe outbound memory ranges for both pcie0 and pcie1
controllers on i.MX95.
The memory window size was incorrectly set to 256MB during initial
bring-up, but the hardware supports up to 4GB of outbound address space
per controller.
Additionally, the ECAM region cannot be mapped as I/O space. Use a
memory-mapped region for I/O space instead, and relocate the 1MB I/O
region to immediately follow the memory region at offset 0xf0000000
within each window.
Update the outbound address space layout per controller as follows:
- 3.5GB 64-bit prefetchable memory
- 256MB 32-bit non-prefetchable memory
- 1MB I/O

Some i.MX boards (i.MX8MP EVK and i.MX95-15x15 EVK) have M.2 connectors
that are physically wired to both USDHC and PCIe controllers. The
default device tree enables USDHC for SDIO WiFi modules and disables
PCIe to avoid regulator conflicts.
Add a common imx-m2-pcie.dtso that can be applied to enable PCIe and
disable USDHC when a PCIe module is installed in the M.2 connector.
This creates the following DTB files:
