Bluetooth: hci_serdev: allow modular drivers

sre · holtmann · commit 081f36a8c2e0 · 2017-04-12T22:12:17.000+02:00
For bluetooth protocol driver only supporting serdev it makes
sense to follow common practice and built them into their own
module.

Such modules need access to hci_uart_register_device and
hci_uart_tx_wakeup for using the common protocol helpers.
