HPET timer not supported on non-x86 targets

[Rafael Folco]

High Precision Event Timer is x86 specific hardware design to replace older PIT and RTC.

Also, '-no-hpet' option makes qemu to fail on non x86 targets.

he libvirt's xml generated has the following:
<timer name="hpet" present="no"/>

The error produced...
libvirtError: internal error: process exited while connecting to monitor: Option no-hpet not supported for this target

For non x86 arch, this bug is affecting test_server_basicops test in Tempest:
tempest.scenario.test_server_basic_ops.TestServerBasicOps.test_server_basicops
No valid host was found.

    Do not add HPET timer config to non x86 targets

    HPET is a harware timer for x86 arch. Also, qemu option '-no-hpet'
    is not supported on non x86 targets. This change does not add hpet
    in the guest's timer config when the arch is not x86_64 or i686.
