REF: rtl_bt: Add firmware and configuration files for the Bluetooth part 
of RTL8723BS


Hello Community

Hardware :
  M8S ARM S812 RTL8723BS
ODIS Wintab8 Intel Atom RTL8723BS


I'm working together with Martin (xdarklight) to get the new kernel 
working for older Android Tv boxes with ARM chipset (Amlogic s802 - 
Amlogic S812; Ubuntu , Debian ).

After Martin has successfully integrated the patch for SDIO controller . 
I got my internal Wlan Adapter (RTL8723BS) working.

We are now also activating the Bluetooth part. But we encountered the 
problem with the config file.  Hans was nice enough to extract the 
RTL8723BS firmware file from the Realtek driver file.

As Hans has already written there are almost no differences in the 
tablet area with config file, I can only confirm this after looking at 
different driver files (Realtek bluetooth UART).

I found only 4 ACPI ID : once the already mentioned OBDA:8723 which is 
the default version ,one for ACER tablet OBDA:0623 and the BESTbuy ( 
Chuwi Hi10 ? ) OBDA:0242 ; in the driver version of 2015/2016 there were 
still 2 config files available(standart and ACER) in the version 2017 
only ONE so that also the Default, ACER and BESTbuy use the same config 
files.

I myself and Martin are currently using the two files from the firmware 
repro successfully.

!! So I ask you to remove the ACPI ID from the file and rename the file 
to RTL8723b_config.bin ; furthermore I ask you to set the reference when 
loading the RTL8723BS Blueooth driver to the RTL8723b_firmware.bin so 
that it corresponds to the standard file name. !!!!
