intel_th: Enumerate Low Power Path output port type
Trace Hub 2.x adds Low Power Path (LPP) output port type, which provides a low power mode trace path from sources to PTI or BSSB. This adds an output subdevice for the LPP port. Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>
