[SRU][H][linux-firmware][PULL] Bluetooth headset random disconnects AX200 (LP: #1933771)

[Impact]

Using several different bluetooth headsets I find that the Bluetooth functionality of the built-in AX200 module of my motherboard keeps randomly disconnecting. I found that this has been fixed in recent Linux firmware updates, but I am not sure that fix has landed yet in Ubuntu Hirsute.

Herewith I am posting the link to exactly the issue I am having: https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1155

And the Linux Firmware commit that resolves this:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=73144e02dcff54529ab42d951de682740d204180

A related Fedora bug:
https://bodhi.fedoraproject.org/updates/FEDORA-2021-93247f3274

It's difficult to relate the upstream kernel version firmware version in which this was fixed (linux-firmware-20210511) to the version of the linux-firmware Ubuntu package (for me). Perhaps someone can comment on whether this has been merged in. I am still experiencing disconnects with 1.197.1 at least.

--

Description:	Ubuntu 21.04
Release:	21.04

linux-firmware:
  Installed: 1.197.1
  Candidate: 1.197.1

I expected:
  Bluetooth headset to remain connected

What happened:
  Bluetooth headset connects, then randomly disconnects and reconnects while playing media

[Test Case]

See above.

[Fix]

Update AX20x firmware blobs.

[Where Problems Could Occur]

New firmware blobs so previously working adapter might now fail.
