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.
