Bluetooth: btnxpuart: Add support to set BD address

This adds support for setting BD address during hci registration. NXP
FW does not allow vendor commands unless it receives a reset command
after FW download and initialization done.

As a workaround, the .set_bdaddr callback function will first send the
HCI reset command, followed by the actual vendor command to set BD
address.

The driver checks for the local-bd-address property in device tree, and
if preset, it sets the HCI_QUIRK_USE_BDADDR_PROPERTY quirk.

With this quirk set, the driver's set_bdaddr callback function is called
after FW download is complete and before HCI initialization, which sends
the hci reset and 3f 22 commands. During initialization, kernel reads
the newly set BD address from the controller.
