arm64: dts: apple: t600x: Disable unused PCIe ports

The PCIe ports are unused (without devices) so disable them instead of
removing them.

All the other DARTs are named foo-dart, so let's keep things consistent.

The PCIe iommu nodes use "dart" as node names. Replace it with the
the standard "iommu" node name as all other iommu nodes.

arm64: dts: apple: Add ADMAC resets on t8103/t600x

There's a shared reset for the ADMAC and MCA peripherals. The MCA node
already describes it, and being a shared reset it is important we
describe it on the ADMAC node too.

arm64: dts: apple: Add initial t6000/t6001/t6002 DTs

These SoCs are found in Apple devices with M1 Pro (t6000), M1 Max
(t6001) and M1 Ultra (t6002).

t6000 is a cut-down version of t6001, so the former just includes the
latter and disables the missing bits (This is currently just one PMGR
node and all of its domains.

t6002 is two connected t6001 dies. The implementation seems to use
t6001 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 execption is the
NVMe controller which resides on the second die. Its nodes are in a
separate file.
