Subject: [PATCH 0/5] Apple device tree sync from downstream kernel

This series pulls changes from the downstream device trees which are
supported in upstream kernel.
Most importantly it fixes the PCIe description for a specific iMac model
(iMac M1, 2 USB-C ports, 2021). This is worked around in the downstream
kernel by not disabling the port. In preparation for submitting M2
Pro/Max/Ultra devices trees I investigated the issue on the similarly
affected M2 Pro Mac mini and fixed it this way.
It completes the Wlan/BT device nodes for t600x based devices and adds
the missing 15-inch Macbook Air (M2, 2023).

Checkpatch emits following warnings:

WARNING: DT compatible string vendor "pci14e4" appears un-documented --
check ./Documentation/devicetree/bindings/vendor-prefixes.yaml

Which I chose to ignore. `vendor-prefixes.yaml` prefixes contains no
other mapping for PCI vendor code and the list of ignored prefixes
forbids extending it. Both options feel wrong though. "pci${vendor}" is
clearly a vendor prefix but duplicating the PCI vendor data base feels
wrong. `vendor-prefixes.yaml` currently does not contain and PCI vendor
aliases.
