The Bluetooth controller with USB ID 0b05:1825 found on ASUS
systems uses a Qualcomm QCA Rome chipset, but is currently matched
only by the generic Bluetooth USB entry.

Without BTUSB_QCA_ROME, the driver does not load the QCA rampatch and
NVM firmware. BLE scanning also repeatedly reports:

    Bluetooth: hci0: unexpected event for opcode 0x2005

Mark the device as BTUSB_QCA_ROME with wideband speech support, in
line with the other QCA Rome USB IDs.

Same issue as https://github.com/bluez/bluetooth-next/pull/833 but
with different device id. After patching bluetooth is working fine,
no unexpected events in log.

Tested on: Qualcomm Atheros QCA6174 SoC integrated in motherboard
ASUS Z170I PRO GAMING, USB device id: 0b05:1825
