version filed in generic distributor has following values,

/* Values for gic_version in Generic Distributor  (ACPI 6.0) */

enum acpi_madt_gic_ver_type
{
         ACPI_MADT_GIC_VER_UNKNOWN       =3D 0,
         ACPI_MADT_GIC_VER_V1            =3D 1,

         ACPI_MADT_GIC_VER_RESERVED      =3D 5     /* 5 and greater are=
=20
reserved */
};

should we put it here, or locate it to ARM64 arch related head
file?

Thanks
Hanjun
