Janne Grunau 828fe6b624 dt-bindings: arm: apple: Add t8112 j413/j473/j493 compatibles
This adds the following apple,t8112 platforms:

- apple,j413 - MacBook Air (M2, 2022)
- apple,j473 - Mac mini (M2, 2023)
- apple,j493 - MacBook Pro (13-inch, M2, 2022)

The sort order logic here is having SoC numeric code families in release
order, and SoCs within each family in release order:

- t8xxx (Apple HxxP/G series, "phone"/"tablet" chips)
  - t8103 (Apple H13G/M1)
  - t8112 (Apple H14G/M2)
- t6xxx (Apple HxxJ series, "desktop" chips)
  - t6000 (Apple H13J(S)/M1 Pro)
  - t6001 (Apple H13J(C)/M1 Max)
  - t6002 (Apple H13J(D)/M1 Ultra)

ARM platforms using SoCs designed by Apple Inc., branded "Apple Silicon".
This currently includes devices based on the "M1" SoC:
- Mac mini (M1, 2020)
- MacBook Pro (13-inch, M1, 2020)
- MacBook Air (M1, 2020)
- iMac (24-inch, M1, 2021)
Devices based on the "M2" SoC:
- MacBook Air (M2, 2022)
- MacBook Pro (13-inch, M2, 2022)
- Mac mini (M2, 2023)
And devices based on the "M1 Pro", "M1 Max" and "M1 Ultra" SoCs:
- MacBook Pro (14-inch, M1 Pro, 2021)
- MacBook Pro (14-inch, M1 Max, 2021)
- MacBook Pro (16-inch, M1 Pro, 2021)
- MacBook Pro (16-inch, M1 Max, 2021)
- Mac Studio (M1 Max, 2022)
- Mac Studio (M1 Ultra, 2022)
The compatible property should follow this format:
compatible = "apple,<targettype>", "apple,<socid>", "apple,arm-platform";
<targettype> represents the board/device and comes from the `target-type`
property of the root node of the Apple Device Tree, lowercased. It can be
queried on macOS using the following command:
$ ioreg -d2 -l | grep target-type
<socid> is the lowercased SoC ID. Apple uses at least *five* different
names for their SoCs:
- Marketing name ("M1")
- Internal name ("H13G")
- Codename ("Tonga")
- SoC ID ("T8103")
- Package/IC part number ("APL1102")
Devicetrees should use the lowercased SoC ID, to avoid confusion if
multiple SoCs share the same marketing name. This can be obtained from
the `compatible` property of the arm-io node of the Apple Device Tree,
which can be queried as follows on macOS:
$ ioreg -n arm-io | grep compatible
