soc/intel/tigerlake: Add CNVi Bluetooth flag at devicetree entry
FSP has added the Cnvi BT Core enabling in addition to the existing
CnviMode. This change adds the flag at the soc config side (i.e.
soc_intel_tigerlake_config for devicetree). Also, there is no longer PCI host
interface for BT. Therefore, BT core should not use the pci port status to turn
on/off.
TEST: BT enumeration is checked using 'lsusb -d 8087:0026' from OS to make
sure BT is turned on.
