On the Broadwell. Bay Trail, Cherry Trail, and Braswell platforms
the CPU has direct access to the SST sound device, so the device
doesn't appear on the PCI bus. So the only way to detect these
devices is to inspect the ACPI device list.

As there are only a few devices involved, include the device table
here rather than extending ldetect-lst.

Significantly speeds up service_harddrake, and hence Live ISO boot, due
to many calls to detect_devices::probeall().

  so if cpu is not supporting it, install the desktop586 kernel

it looks like not all KVM GUIes result in the same result with
systemd-detect-virt
let's handle both cases
