FABRIC.md: aarch64 keyboard punch list -- GIC-SPI derivation, no landmine

Live-probed GICD_ITARGETSR before starting 4.3.5d/e; survived cleanly,
unlike riscv64's PLIC (4.3.5a). Decoded QEMU's own virt DTB for the PCI
slot->SPI interrupt-map routing table and closed-form formula. Amended
4.3.5d's circular acceptance criterion to a synthetic GICD_ISPENDR probe
(mirrors 4.3.5b's fix for the same problem), and wrote the full 4.3.5e
virtio-input execution plan: device ID 0x1052, the real virtio_input_event
struct, the mandatory ISR-status read, and the pci_enable() interrupt-
disable-bit gap.
