Added a device tree for the MacBook Neo, which uses the t8140 SoC
(A18 Pro) also found in the iPhone 16 Pro.
The device tree has a minimal set of devices limited to CPU cores,
interrupt controller, watchdog, serial and framebuffer.
Using the macOS 26.6.2 iBoot/firmware, the machine 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.
