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.
Fixes: 7c77ab91b33d ("arm64: dts: apple: Add missing M1 (t8103) devices")
