Bluetooth: Support HCI_QUIRK_EXTERNAL_CONFIG for hci_vhci driver

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

This adds support for configuring the hci_vhci virtual controllers
to require a setup stage using HCI_QUIRK_EXTERNAL_CONFIG. With this
option the virtual controller will start out as unconfigured.
