rtl_bt: Add rtl8723bs_config-OBDA0623.bin symlink

Some x86/ACPI devices such as the Acer Aspire Switch 10E (SW3-016),
use an alternative ACPI hardware-id (HID) for the BT part of the
RTL8723BS chip.

Instead of using the standard OBDA8723 HID this device uses a HID
of OBDA0623. Despite using a different HID it does work fine with
the default config settings from the rtl8723bs_config-OBDA8723.bin
file. Add a symlink to that file, to fix BT not working on this
device due to a missing config file.
