[Impact]
BT fails to enable again after disabled it by hotkey with the following message
   Bus 001 Device 004: ID 8087:0029 Intel Corp.
[248987.643125] usb 1-10: device descriptor read/64, error -110

[Fix]
Found the updated firmware fixes the issue

[Test]
Verify on the machine couple days, and can't duplicate the issue anymore.

[Regression Potential]
Low, the system keeps running for 5 days, and pass s3 tests 30 times,
everything works well.

[Misc]
The firmware for the wifi/bt card is intel/ibt-20-0-3.*, but
intel/ibt-20-0-4.* have identical md5sum. To avoid the following new
cards require the new fw_revision, so SRU both of them.
