btbcm_finalize() does a re-init of the controller, which is almost the
same as the initial init. Modify btbcm_initialize() so that it can be
used for this re-init and modify btbcm_finalize() to use it.
As an added bonus this also makes the dev_info from btbcm_finalize()
use the proper hw_name instead of always printing "BCM".

Make btbcm_initialize() also work for USB connected device,
btbcm_initialize() and btbcm_setup_patchram() are quite similar,
this is a preparation patch for making btbcm_setup_patchram() use
btbcm_initialize() to remove the code duplication.

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':

The Broadcom Bluetooth controllers have the chip name included in the
ROM firmware or later in the patchram firmware. For debugging purposes
read the local name and print it out. This is only done during setup
stage and only once before loading the firmware and once after loading

For the Broadcom based controllers from Apple, the name is only read once
after determining the chip id.

The commit 7bee8b08c4 allows the Read Verbose Config Info to fail
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
to bring the controller in full Bluetooth mode.
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.

Commit 1c8ba6d013 moved around the setup code for broadcomm chips,
and also added btbcm_read_verbose_config() to read extra information
about the hardware. It's returning errors on some macbooks:
Bluetooth: hci0: BCM: Read verbose config info failed (-16)
Which makes us error out of the setup function. Since this
probe isn't critical to operate the chip, this patch just changes
things to carry on when it fails.

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().

Move request/release_firmware() out of btbcm_patchram().
This allows a better error management, if request_firmware() returns an
error then the controller will be used without firmware loading and 0 is
returned.
This will imply to change btbcm_patchram() to accept a firmware instead
of firmware name.

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().
