Bluetooth: Introduce to_hci_dev()
We currently use dev_set_drvdata to keep a pointer to ourself. This
doesn't make sense as we are the bus and not a driver. Therefore,
introduce to_hci_dev() so we can get a struct hci_dev pointer from a
struct device pointer.
dev_set/get_drvdata() is reserved for drivers that provide a device and
not for the bus using the device. The bus can use simple pointer
arithmetic to retrieve its private data.
