hw/intc/arm_gic: Add external IRQ lines for VIRQ and VFIQ
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.

hw/intc/arm_gicv3: ARM GICv3 device framework
This patch includes the device class itself, some ID register
value functions which will be needed by both distributor
and redistributor, and some skeleton functions for handling
interrupts coming in and going out, which will be filled in
in a subsequent patch.

hw/intc/arm_gicv3: Move irq lines into GICv3CPUState structure
Move the GICv3 parent_irq and parent_fiq pointers into the
GICv3CPUState structure rather than giving them their own array.
This will make it easy to assert the IRQ and FIQ lines for a
particular CPU interface without having to know or calculate
the CPU index for the GICv3CPUState we are working on.

hw/intc/arm_gic_common: Configure IRQs as NS if doing direct NS kernel boot
If we directly boot a kernel in NonSecure on a system where the GIC
supports the security extensions then we must cause the GIC to
configure its interrupts into group 1 (NonSecure) rather than the
usual group 0, and with their initial priority set to the highest
NonSecure priority rather than the usual highest Secure priority.
Otherwise the guest kernel will be unable to use any interrupts.
Implement this behaviour, controlled by a flag which we set if
appropriate when the ARM bootloader code calls our ARMLinuxBootIf
interface callback.
