[PATCH v2 04/15] tests: acpi: q35: test for x2APIC entries in SRAT

[Igor Mammedov <imammedo@redhat.com>]

Set -smp 1,maxcpus=288 to test for ACPI code that
deal with CPUs with large APIC ID (>255).

PS:
Test requires KVM and in-kernel irqchip support,
so skip test if KVM is not available.

Signed-off-by: Igor Mammedov <imammedo@redhat.com>

v3:
  - add dedicated test instead of abusing 'numamem' one
  - add 'kvm' prefix to the test name
      ("Michael S. Tsirkin" <mst@redhat.com>)
v2:
  - switch to qtest_has_accel() API
