From: Gayatri Kammela <gayatri.kamm...@intel.com>
Just like Ice Lake, Tiger Lake uses Cannon Lake's LTR information
and supports a few additional registers. Hence add the LTR registers
specific to Tiger Lake to the cnp_ltr_show_map[].
Also adjust the number of LTR IPs for Tiger Lake to the correct amount.
