soc/intel/ptl: Add Wildcat Lake SoC device tree

Browse source 
This patch introduces a new chipset device tree file for Wildcat
Lake SoC.

Key changes:
 - Copy the Panther Lake chipset.cb to chipset_wcl.cb and update
   it with device information specific to the Wildcat Lake SoC.
   1) Remove following devices:
        - Ipu         - 00:05.0
        - Tbt Rp      - 00:07.2 & 00:07.3
        - Type-C xDCI - 00:0d.1
        - Tcss Dma    - 00:0d.3
        - Pci Rp      - 00:1c.4 to 00:1c.7
                      - 00:06.2 & 00:06.3
        - Two TCSS USB ports
   2) Remove Panther Lake Power limits config and add placeholder
      for WCL config.
 - Guard removed TCSS port references in the shared SoC code with
   Kconfig.
 - Rename Panther Lake chipset device tree to chipset_ptl.cb to
   align with the new device tree naming.
 - Update Kconfig to select the newly added chipset device tree
   file when the Wildcat Lake SoC is in use.
