Bluetooth: btusb: Update firmware filename for Intel 9x60 and later
The format of Intel Bluetooth firmware for bootloader product is
ibt-<hw_variant>-<device_revision_id>.sfi and .ddc.
But for the SKU's 9x60, there a 3 variants of FW, which cannot be
differentiated just with hw_variant and devision_revision_id.
So to pick the appropriate FW file for 9x60 SKU's, it will be
differentiated using hw_variant, hw_revision and fw_revision rather
than hw_variant and device_revision_id only.
Format will be like this:
ibt-<hw_variant>-<hw_revision>-<fw_revision>.sfi and .ddc
