aarch64: GIC SPI wiring for virtio-input (item 4.3.5d)

Browse Source 
Punch list §25 item 4.3.5d complete.

New apic_spi_enable(intid) generalizes item 0.6's PPI-only sequence to one
explicit SPI (IPRIORITYR/ISENABLER/ITARGETSR, ICFGR read-checked not
written). Verified via a software-pended SPI (GICD_ISPENDR, no device
needed) through the existing generic IRQ dispatch, which needed no changes.
Found and fixed a real bug during verification: PSTATE.I is still set at
apic_init()'s point in boot, so the first self-test run correctly latched
but never took the interrupt. Self-test code reverted after capturing
evidence -- interrupts.c has zero net diff, only apic_spi_enable() remains,
unused until 4.3.5e. Three-arch acceptance boot clean.
