BCM4356 devices soldered onto the PCB (non-removable) use an UART
connection for bluetooth, such as the Rock960, but it also advertise
btsdio support as a sdio function.

Macro module_sdio_driver is used for drivers whose init and exit paths
only register and unregister to SDIO API. So remove boilerplate code to
make code simpler by using module_sdio_driver.

BCM43341 devices soldered onto the PCB (non-removable) always (AFAICT)
use an UART connection for bluetooth. But they also advertise btsdio
support on their 3th sdio function, this causes 2 problems:
1) A non functioning BT HCI getting registered
2) Since the btsdio driver does not have suspend/resume callbacks,
mmc_sdio_pre_suspend will return -ENOSYS, causing mmc_pm_notify()
to react as if the SDIO-card is removed and since the slot is
marked as non-removable it will never get detected as inserted again.
Which results in wifi no longer working after a suspend/resume.
This commit fixes both by making btsdio ignore BCM43341 devices
when connected to a slot which is marked non-removable.

The HCI_BREDR naming is confusing since it actually stands for Primary
Bluetooth Controller. Which is a term that has been used in the latest
standard. However from a legacy point of view there only really have
been Basic Rate (BR) and Enhanced Data Rate (EDR). Recent versions of
Bluetooth introduced Low Energy (LE) and made this terminology a little
bit confused since Dual Mode Controllers include BR/EDR and LE. To
simplify this the name HCI_PRIMARY stands for the Primary Controller
which can be a single mode or dual mode controller.

The new hci_skb_pkt_* wrappers are mainly intented for drivers to
require less knowledge about bt_cb(sbk) handling. So after converting
the core packet handling, convert all drivers.

Setting and clearing of HCI_RUNNING flag in each and every driver is
just duplicating the same code all over the place. So instead of having
the driver do it in their hdev->open and hdev->close callbacks, set it
globally in the core transport handling.

In all callbacks for hdev->send the status of HCI_RUNNING is checked. So
instead of repeating that code in every driver, move the check into the
hci_send_frame function before calling hdev->send.

The Socket Bluetooth SDIO cards are branded versions of Toshiba SD-BT2
and they do not support sending HCI_Reset as first command. To make
this card work the HCI_QUIRK_RESET_ON_CLOSE quirk needs to be set
before registering the controller.

Instead of masking hdev inside the skb->dev parameter, hand it
directly to the driver as a parameter to hdev->send. This makes
the driver interface more clear and simpler.
This patch fixes all drivers to accept and handle the new parameter
of hdev->send callback. Special care has been taken for bpa10x
and btusb drivers that require having skb->dev set to hdev for
the URB transmit complete handlers.

To avoid casting skb->dev into hdev, just let the drivers provide
the hdev directly when calling hci_recv_frame() function.
This patch also fixes up all drivers to provide the hdev.

After unregistering an hci_dev object a bluetooth driver does not have
any callbacks in the hci_dev structure left over. Therefore, there is no
need to keep a reference to the module.
Previously, we needed this to protect the hci-destruct callback.
However, this callback is no longer available so we do not need this
owner field, anymore. Drivers now call hci_unregister_dev() and they
are done with the object.

Instead of waiting for the hdev object to get freed we now free the
private driver-internal data on SDIO shutdown. This allows us to remove
the obsolete hci-destruct callback and free our data object right away
after calling hci_unregister_dev(). The HCI-core does not call any
callbacks after this so we are never called again and can safely exit
the module.

With the introduction of CONFIG_DYNAMIC_PRINTK_DEBUG it is possible to
allow debugging without having to recompile the kernel. This patch turns
all BT_DBG() calls into pr_debug() to support dynamic debug messages.
As a side effect all CONFIG_BT_*_DEBUG statements are now removed and
some broken debug entries have been fixed.
