Salil Mehta 549c9a9dcb hw/acpi: Update GED _EVT method AML with CPU scan 
OSPM evaluates _EVT method to map the event. The CPU hotplug event eventually
results in start of the CPU scan. Scan figures out the CPU and the kind of
event(plug/unplug) and notifies it back to the guest. Update the GED AML _EVT
method with the call to method \\_SB.CPUS.CSCN (via \\_SB.GED.CSCN)

Architecture specific code [1] might initialize its CPUs AML code by calling
common function build_cpus_aml() like below for ARM:

build_cpus_aml(scope, ms, opts, xx_madt_cpu_entry, memmap[VIRT_CPUHP_ACPI].base,
               "\\_SB", "\\_SB.GED.CSCN", AML_SYSTEM_MEMORY);
