Subject: [PATCH] Bluetooth: btusb: Add a quirk for BCM43142A0 (105b:e065)

USB Bluetooth module by Foxconn International, Inc. (USB IDs: 105b:e065)
is based on BCM43142A0 chip by Broadcom. This module can be found, for
example, in Lenovo B590 and a few other laptops.

This device requires firmware update to be operational, so this patch
adds a quirk for it.

With the firmware properly converted and placed:
Bluetooth: hci0: BCM: patching hci_ver=06 hci_rev=0000 lmp_ver=06
lmp_subver=210b
Bluetooth: hci0: BCM: firmware hci_ver=06 hci_rev=00ac lmp_ver=06
lmp_subver=210b
