Enable CONFIG_BT_ATH3K for Atheros AR3012 Bluetooth on generic-x86-64

Describe the issue you are experiencing

Describe the issue you are experiencing

The internal Bluetooth adapter on my ASUS laptop is detected by the HAOS kernel as a USB device, but no Bluetooth HCI controller is created.

The Bluetooth hardware is an Atheros AR3012 with USB ID 04ca:3010.

Home Assistant shows:

No unconfigured Bluetooth adapters found.

The device is correctly detected on USB, but there is no driver bound to the Bluetooth interfaces and /sys/class/bluetooth/ is empty.

I believe the issue is that CONFIG_BT_ATH3K is disabled in the HAOS kernel.
