Subject: [PATCH 0/2] arch: arm64: dts: apple: Disable unused PCIe ports

The t8103 and t600x device trees deleted unused PCIe ports. This was
probably done to replicate Apple's device tree which doesn't has nodes
for most unused hardware.
A more accurate description of the hardware is to disable unused
hardware.

This was discovered during the review of the t8112 device trees in
https://lore.kernel.org/asahi/1ea2107a-bb86-8c22-0bbc-82c453ab08ce@linaro.org/
