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.
