arm64: dts: apple: Add J180d (Mac Pro, M2 Ultra, 2023) device tree
The M2 Ultra in the Mac Pro differs from the M2 Ultra Mac Studio in its
PCIe setup. It uses all available 16 PCIe Gen4 on the first die and 8
PCIe Gen4 lanes on the second die to connect to a 100 lane Microchip
Switchtec PCIe switch. All internal PCIe devices and the PCIe slots are
connected to the PCIe switch.
Each die implements a PCIe controller with a single 16 or 8 lane port.
The PCIe controller is mostly compatible with existing implementation
in pcie-apple.c.
The resources for other 8 lanes on the second die are used to connect
the NVMe flash with the controller in the SoC.
This initial device tree does not include PCIe support.

arm64: dts: apple: Add initial t6020/t6021/t6022 DTs
These SoCs are found in Apple devices with M2 Pro (t6020), M2 Max
(t6021) and M2 Ultra (t6022) and follow the pattern of their M1
counterparts.
arm64: dts: apple: Add initial t6020/t6021/t6022 DTs
These SoCs are found in Apple devices with M2 Pro (t6020), M2 Max
(t6021) and M2 Ultra (t6022) and follow the pattern of their M1
counterparts.
t6020 is a cut-down version of t6021, so the former just includes the
latter and disables the missing bits (This is currently just one PMGR
node and all of its domains).
t6022 is two connected t6021 dies. The implementation seems to use
t6021 with blocks disabled (mostly on the second die). MMIO addresses on
the second die have a constant offset. The interrupt controller is
multi-die aware. This setup can be represented in the device tree with
two top level "soc" nodes. The MMIO offset is applied via "ranges" and
devices are included with preproceesor macros to make the node labels
unique and to specify the die number for the interrupt definition.
Device nodes are distributed over dtsi files based on whether they are
present on both dies or just on the first die. The only exception is the
NVMe controller which resides on the second die. Its nodes are in a
separate file.

arm64: dts: apple: t8103-j457: Fix PCIe ethernet iommu-map
PCIe `port01` of t8103-j457 (iMac, M1, 2 USB-C ports, 2021) is unused
and disabled. Linux' PCI subsystem assigns the ethernet nic from
`port02` to bus 02. This results into assigning `pcie0_dart_1` from the
disabled port as iommu. The `pcie0_dart_1` instance is disabled and
probably fused off (it is on the M2 Pro Mac mini which has a disabled
PCIe port as well).
Without iommu the ethernet nic is not expected work.
Adjusts the "bus-range" and the PCIe devices "reg" property to PCI
subsystem's bus number.
