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.
