platform/x86: intel_pmc_core: Add LTR registers for Tiger Lake

Browse Source 
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.
