Realtek based serial devices.

Changes in v2 (Hans de Goede)
-Keep the depends on BT_HCIUART_SERDEV for BT_HCIUART_3WIRE even if we #ifdef
 the btrtl bits we still need it for hci_uart_[un]register_device()
-Add #ifdef CONFIG_BT_HCIUART_RTL checks to hci_h5.c so that it does not
 reference the rtlbt.c code when BT_HCIUART_RTL is not set, this fixes linker
 errors when BT_HCIUART_RTL is not set, BT_HCIUART_3WIRE=y (builtin) and
 BT_HCIBTUSB_RTL=m, which selects BT_RTL=m, which would end up having the
 btrtl symbols in a module with builtin code referencing it
