[PATCH V2 8/9] platform/x86: intel_pmc_core: Add LTR registers for Tiger Lake

[David E. Box]

From: Gayatri Kammela <gayatri.kammela@xxxxxxxxx>

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.
