The linux device model provides dev_set/get_drvdata so we can use this
to save private driver data.
This also removes several unnecessary casts.

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.

The hdev->type is misnamed and should be actually hdev->bus instead. So
convert it now.

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.
