intel_th: pti: Support Low Power Path output port type
The Low Power Path (LPP) output port type, looks mostly like PTI to the software, with a few additional bits in the control register. This extends the PTI driver to support LPP ports as well. Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>
