intel_th: Add ACPI glue layer
The Trace Hub devices now can be enumerated as ACPI devices, which translates into "Host Debugger mode". There are two IDs: one for PCH Trace Hub, and one for the uncore Trace Hub. These are expected to stay the same across all platforms. Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>
