arm64: dts: apple: Add minimal t8132 (M4) device trees
Added device trees for the following devices:
- apple,j604 - MacBook Pro (14-inch, M4, 2024)
- apple,j623 - iMac (24-inch, 2x USB-C, M4, 2024)
- apple,j624 - iMac (24-inch, 4x USB-C, M4, 2024)
- apple,j713 - MacBook Air (13-inch, M4, 2025)
- apple,j715 - MacBook Air (15-inch, M4, 2025)
- apple,j773g - Mac mini (M4, 2024)
The device trees have a minimal set of devices limited to CPU cores,
interrupt controller, power states, watchdog, serial, pin controller,
i2c and framebuffer.
The device trees for the notebooks add a PWM controller for the keyboard
LED illumination.
Using the macOS 26.6 iBoot/firmware, the Mac mini reliably boots on a
single core using the stock kernel.
Booting with smp requires avoiding the wfi and wfit instructions
in the idle loop and `delay()` respectively, since those instructions
cause a loss of architectural state on the secondary cores, and even
then boot is unreliable.
