So basically move the serdev implementation from hci_ll.c into its
own driver and make hci_ll hci_uart based only? That effectively
means, that we have two implementations of the protocol. I don't
think this will improve maintainability, since then bugs needs to
be fixed in two places? Note, that we have a couple of drivers
with serdev+hci_uart by now:
for file in $(grep -l serdev drivers/bluetooth/hci_*c) ; grep -l hci_uart_register_proto "${file}"
hci_bcm.c
hci_h5.c
hci_ldisc.c
hci_ll.c
hci_mrvl.c
hci_qca.c
