To realize CPU hotplug, the cpus aml within ACPI DSDT should contain
_MAT mathod, which is equal to the GICC struct in ACPI MADT. Factor
out the GICC building code from ACPI MADT and reuse it in build_cpus_aml.

(cherry picked from commit f2b68e8adc98f8db20b1edc84b8f485975ed987c)
This series is an attempt to provide CPU hotplug support on ARM
virt platform. This is based on ACPI GED device.
We should enable ACPI support, and use vGICv3 and 64bit CPU to
support CPU hotplug.
Under KVM accel, the KVM vCPUs is pre-created. Besides, vGIC IRIs
is pre-created too. However, QEMU vCPU objects are defer-created.
