Bluetooth: btmtk: Declare MT7920 (MT7961 1a) Bluetooth firmware
btmtk_fw_get_filename() constructs the firmware name at runtime, so for
the MT7920 variant (dev_id 0x7961 with fw_flavor set) it requests
"mediatek/BT_RAM_CODE_MT7961_1a_2_hdr.bin" without ever declaring it via
MODULE_FIRMWARE(). Tools that select firmware from module metadata (e.g.
"modinfo -F firmware") therefore omit this blob, so request_firmware()
fails and Bluetooth does not initialise on MT7920, even though the file
is present in linux-firmware.
Declare it with MODULE_FIRMWARE(), as the mt76 driver already does for
the corresponding MT7920 wifi firmware.
