Subject: [PATCH v2] Bluetooth: btrtl: btmrvl: Fix firmware filename for rtl chipset

Firmware for rtl chipset is as part of the linux-firmware repository
in dir linux-firmware/rtl_bt. Today, the rtl8761a_config,
rtl8821a_config, rtl8723b_config and rtl8723bs_config files are used
in btrtl, but it doesn't actually exist, which causes errors like:

bluetooth: Direct firmware load for rtl_bt/rtl8821a_config.bin
           failed with error -2

According to the files in the rtl_bt directory in the Linux firmware,
fixes the driver to load correct firmware file for rtl.
