FROMGIT: Bluetooth: qca: Add BT FW build version to kernel log

Firmware version is critical for bug triage. Users reporting issues
typically share dmesg output rather than debugfs contents, requiring
extra communication rounds to collect this information. Log the FW
build version directly to the kernel log so it is immediately
available in bug reports.

Example output:

  Bluetooth: hci0: QCA FW build version:
    BTFW.MOSELLE.1.1.3-00106-MSL_PATCHZ-1
