The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

WCN399x chips are coex chips, it needs a VS pre shutdown
command while turning off the BT. So that chip can inform
BT is OFF to other active clients.

QCA BTSOC NVM is a customized firmware file and different vendors may
want to have different BTSOC configuration (e.g. Configure SCO over PCM
or I2S, Setting Tx power, etc.) via this file. This patch will allow
vendors to download different NVM firmware file by reading a device
property "firmware-name".

Latest qualcomm chips are not sending an command complete event for
every firmware packet sent to chip. They only respond with a vendor
specific event for the last firmware packet. This optimization will
decrease the BT ON time. Due to this we are seeing a timeout error
message logs on the console during firmware download. Now we are
injecting a command complete event once we receive an vendor specific
event for the last RAM firmware packet.

Redefinition of qca_uart_setup will help future Qualcomm Bluetooth
SoC, to use the same function instead of duplicating the function.
Added new arguments soc_type and soc_ver to the functions.
These arguments will help to decide type of firmware files
to be loaded into Bluetooth chip.
soc_type holds the Bluetooth chip connected to APPS processor.
soc_ver holds the Bluetooth chip version.

Some of the QCA BTSoC ROME functions, are used for different versions
or different make of BTSoC's. Instead of duplicating the same functions
for new chip, update names of the functions that are used for both
chips to keep this generic and would help in future when we would have
new BT SoC. To have generic text in logs updated from ROME to QCA where
ever possible. This avoids confusion to user, when using the future
Qualcomm Bluetooth SoC's. Updated BT_DBG, BT_ERR and BT_INFO with
bt_dev_dbg, bt_dev_err and bt_dev_info where ever applicable.

This patch adds rampatch download compatibility for ROME >= 3.2.
Starting with ROME 3.2, the 'download mode' field of the rampatch
header indicates if the controller acknowledges (or not) the received
rampatch segments. If not, we need to send all the segments without
expecting any event from the controller (except for the last segment).
Goal is (I assume) to speed-up rampatch download.
This fixes BT on Dragonboard-600c P2 which includes the following BT
controller:
hci0: ROME Patch Version Request
hci0: Product:0x00000008
hci0: Patch :0x00000111

This is for supporting BT for QCA ROME with vendor specific
HCI commands and initialization on the chip. This will have
USB/UART implementation both, but for now, adding UART vendor
specific commands to patch downloading and set Bluetooth device
address using vendor specific command.
