LX2160 SoC pci-e controller supports 64-bit memory regions up to 16GB,
32-bit regions up to 3GB and 16-bit regions up to 64k.
For each pci-e controller:
- extend the existing 32-bit regions to 3GB size
- drop IORESOURCE_BUSY flag
- add 64-bit region
See [1] and [2] for boot messages showing ranges before and after.
IORESOURCE_BUSY is dropped since it has no effect when specified in dts.
For LX2160A Silicon revision 1, the 16GB 64-bit area is split into 4
pieces, because the layerscape pcie driver fails to program atu for
larger ranges [3].
Similar memory allocation with similar flags was tested with UEFI and ACPI
on pcie3 and pcie5, on a variety of nxp vendor fork versions.
This patch was tested on Linux v7.1-rc1 and u-boot, with two pcie cards:
- pcie5: Radeon Pro WX2100
- pcie3: ADATA NVME
This fixes allocation of large, and 64-bit BARs as requested by many pci
cards - especially graphics processors or AI accelerators, e.g.:
[ 2.941187] pci 0000:01:00.0: BAR 0: no space for [mem size 0x200000000 64bit pref]
[ 2.948834] pci 0000:01:00.0: BAR 0: failed to assign [mem size 0x200000000 64bit pref]

LX2160A and LX2162A are different pakages of the same silicon.
While LX2160A had two revisions, LX2162A was released later based on
LX2160A revision 2.
Commit a8fe6c8dfc40 ("arm64: dts: fsl-lx2160a: add rev2 support") has
added a new soc dtsi for revision 2.
Update LX2162A Clearfog description to use revision 2 dtsi.
Fixes: 5093b190f9ce ("arm64: dts: freescale: Add support for LX2162 SoM & Clearfog Board") # no-stable

The SoC dtsi has always enabled serdes block 1, enabled dpmac and
disabled pcie nodes.
Drop the superfluous status properties on these nodes.
Further drop crypto alias as SoM dtsi already set it.

The LX2162A Clearfog board has a green LED on each of four SFP ports.
Describe in device-tree that their colour is green and function "lan".

The SolidRun LX2160A Twins board supports two configurations, one with
with a sinle CEX-7 module, and one with two (dual).
The dual configuration was not yet tested.
Add binding for the single variant only.

The dts version tag should only appear in the top level dts file.
Since the cex-7 module and clearfog-itx are shared code intended for
inclusion, drop their dts version tags.

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.

LX2160A SoC dtsi defines rather conservative thermal trip points,
alert at 85°C and critical at 95°C.
This is okay for most boards, however the SoC maximum junction
temperature is 105°C in both commercial and industrial version.
Industrial grade boards need to change the thresholds to avoid premature
thermal shutdown in high-temeprature environments.
Add labels to all thermal trip point nodes, enabling board dts to
reference them and modify properties.

The LX2160 CEX-7 module integrates in i2c bus multiplexer. Some of its
channel nodes have labels, others do not.
Add descriptive labels to the unlabeled channels, allowing other board
dts to reference them for example in aliases.

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
This patch adds 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
