This SRU is only for focal, in the Jammy, the sof-firmware is in the
package firmware-sof-signed instead of linux-firmware, so will send a
SRU to firmware-sof-signed for Jammy.

[Impact]
we have a Dell ADL laptop which has sdw audio, but there is no camera
and no internal digital mic in this machine, the current asoc driver
can't work on this machine, the speaker and headset couldn't work.

[Fix]
Backport a tplg file which is specific to this mahcine

[Test]
Install the patched linux-firmware and boot the latest oem-5.14 kernel
on the machine, check dmesg, it loads the correct tplg, and
test speaker and headset, all work well.

[Where problems could occur]
This SRU is adding a new tplg file, it has no chance to introduce
a regression.
