BCM2076B1 appears to use 20:76:A0:00:56:79 as default address.
This address is used by at least 5 devices with the AMPAK AP6476
module and is also suspicious because it starts with the chip name
2076 (followed by a different revision A0 for some reason).
Add it to the list of default addresses and leave it up to the
user to configure a valid one.

The BCM43341B has the default MAC address 43:34:1B:00:1F:AC if none
is given. This address was found when enabling Bluetooth on multiple
Intel Edison modules. It also contains the sequence 43341B, the name
the chip identifies itself as. Using the same BD_ADDR is problematic
when having multiple Intel Edison modules in each others range.
The default address also has the LAA (locally administered address)
bit set which prevents a BNEP device from being created, needed for
BT tethering.
Add this to the list of black listed default MAC addresses and let
the user configure a valid one using f.i.

btbcm_setup_patchram() was using the upper nibble of the revision code to
determine if we are dealing with an uart or USB connected bcm-bt device,
but just as btbcm_initialize() has started accepting 1 and 2 as uart
connected devices, I've now encountered an USB connected device (0a5c:216c)
which has 0 in the upper nibble. So it seems that the upper nibble is not
really a reliable indicator of the bus type.
Instead check hdev->bus which does give us a reliable indication. This
fixes the patchram code trying to load the patchram by the fallback BCM.hcd
filename, now it correctly requests BCM43142A0-0a5c-216c.hcd.

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':

gracefully and not cause the controller setup to abort. It seems the
reason that command failed in the first place was the missing HCI Reset

Apple Bluetooth controllers start out in HID mode and when in that mode
the Read Verbose Config Info command is not allowed. Sending HCI Reset
switches the controller into full HCI mode.

Firmware loading may reset the controller UART speed and needs to set
host UART speed back to init speed.
UART drivers setup is split in 3 parts:
- btbcm_initialize() resets the controller and returns the firmware
name based on controller revision and sub_version.
- btbtcm_patchram() (already existing and public), which takes the
firmware name as parameter, requests the firmware and loads it to
the controller.
- btbcm_finalize() which resets the controller, reads local version
and checks if the controller address is a default one or not.
Remove firmware name retrieval for UART controllers from
btbcm_setup_patchram().

Remove test of command reply status as it is already performed by
__hci_cmd_sync().
__hci_cmd_sync_ev() function already returns an error if it got a
non-zero status either through a Command Complete or a Command
Status event.
For both of these events the status is collected up in the event
handlers called by hci_event_packet() and then passed as the second
parameter to req_complete_skb(). The req_complete_skb() callback in
turn is hci_req_sync_complete() for __hci_cmd_sync_ev() which stores
the status in hdev->req_result. The hdev->req_result is then further
converted through bt_to_errno() back in __hci_cmd_sync_ev().
