[PATCH v2 2/2] Bluetooth: btbcm: Add Synaptics 4384 chip support

Add support for the Synaptics 4384 Bluetooth controller
by adding the corresponding chip IDs.

Tested on the VIM3 platform. Verified that the controller initializes
successfully and that firmware loading and basic Bluetooth operation
work as expected.

The VIM3 is a Khadas single-board computer that I used as the host
platform for testing the BCM4384 Bluetooth controller.
