This patch adds the device ID for the bluetooth chip used in the
AMPAK AP6212 WiFi+Bluetooth module. The AP6212 is used on several
BananaPi boards, e.g. M2-Ultra.

The AP6212 is a combo module, where the WiFi chip is identified as
BCM43430A0 whereas the Bluetooth chip identifies itself as 4343A0. Note,
the missing '0' before the 'A0'.

The AP6212 needs a firmware blob. Loading the provided firmware file
from the BananaPi vendor, the adapter name is printed as
'BCM4343A0 26MHz AP6212_CL1-0061':
