The GICv3 support for virtualization includes an outbound maintenance interrupt signal which is asserted when the CPU interface wants to signal to the hypervisor that it needs attention. Expose this as an outbound GPIO line from the CPU object which can be wired up as a physical interrupt line by the board code (as we do already for the CPU timers).

Augment the GIC's QOM device interface by adding two new sets of sysbus IRQ lines, to signal VIRQ and VFIQ to each CPU. We never use these, but it's helpful to keep the v2-and-earlier GIC's external interface in line with that of the GICv3 to avoid board code having to add extra code conditional on which version of the GIC is in use.

Linux for arm64 v4.10 and later will complain if the ECAM config space is not reserved in the ACPI namespace: acpi PNP0A08:00: [Firmware Bug]: ECAM area [mem 0x3f000000-0x3fffffff] not reserved in ACPI namespace The rationale is that OSes that don't consume the MCFG table should still be able to infer that the PCI config space MMIO region is occupied. So update the ACPI table generation routine to add this reservation.

Using -cpu cortex-a9 (or any other unsupported CPU) with the virt board will cause QEMU to segmentation fault. This bug was introduced in commit 9ac4ef77, which incorrectly added a NULL terminator when converting the VirtBoardInfo array into a simple array of strings defining the valid CPUs. The cpuname_valid() loop already has a termination condition based on ARRAY_SIZE, so the NULL is spurious and causes the strcmp() to segfault if we reach it. Delete the NULL.

The SPI controller of the AST2400 SoC has less registers. So we can adjust the size of the memory region holding the registers depending on the controller type.
