[PATCH 0/1][SRU][B] linux-firmware: Update firmware file for Intel Bluetooth 9560

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/1829737

[Impact]
The firmware blob for Intel Bluetooth 9560/9462 is versioned 20.30.0.1
is not compatible with kernel version >= 4.19 and will cause failure to
pair BT 4.0 devices.

[Fix]
29a536a02cad linux-firmware: Update firmware file for Intel Bluetooth 9560

Above upstream change contains latest firmware file for Intel Bluetooth
9560 that fixes HID pairing in recent kernel versions.

[Test Case]
Copy ibt-17-16-1.sfi blob to /lib/firmware/intel and do a cold boot to
reload firmware. One should find following message in dmesg:

  Bluetooth: hci0: Bootloader revision 0.1 build 42 week 52 2015

This indicates firmware reload has been activated. For further warm
boots, kernel would dump updated revision:

  Bluetooth: hci0: Firmware revision 0.1 build 184 week 15 2019

And perform BT 4.0 device pairing for functional tests.

Tested blob against following kernel versions:
* 5.0.0-1004-oem-osp1
* 5.0.0-15-generic
* 4.18.0-20-generic
* 4.15.0-1038-oem
* 4.15.0-50-generic

[Regression Risk]
Low. This affects only Intel JeffersonPeak Bluetooth chip series, namely
9461/9462/9560, which are the hardware variants to be fixed.

[Misc]
Affected linux-firmware package series:
* Trusty: N/A
* Xenial: REL0186
  * 4.4.0-1480generic (not supported)
  * 4.15.0-50-generic (not affected)
