soc/intel/pantherlake: Add TDP mappings for Panther Lake-U SKUs

Browse source 
This commit addresses incorrect Thermal Design Power (TDP) mappings for
Panther Lake-U SKUs. Both 15W and 25W TDPs are now correctly mapped to
the same Power Limit configurations, ensuring consistent handling of
these SKUs.

Below is the collection of documents utilized to address this issue:
1. 815002 Panther Lake H Processor - External Design Specification
   Revision. 1.52
2. 813278 Panther Lake H Power Map - Rev 1p6

BUG=None
TEST=Do not see error log "Could not find the SKU power map" and warning
     "Skipped power limits configuration for SA PCI ID: 0xb003"
