soc/intel/apollolake: Fix BUG-message when checking for XDCI device
The current check for XDCI enabled uses a static device path to an internal PCI device at a very late point in the boot flow. At this time the devicetree has been processed and disabled devices have been already removed. If this device (00:15.1, XDCI) is disabled in devicetree this will trigger the message 'BUG: check_xdci_enable requests hidden 00:15.1' in the log. This looks weird and is wrong since it is not a bug to disable this device when it is not needed. To avoid this look up the devicetree by a tree walk instead of using a static value for the devicetree.
