[SRU][linux-firmware][B/D/E/unstable][PATCH 0/1] update firmware for sound sof driver to fix the hang issue on several Dell machines

[Hui Wang]

BugLink: https://bugs.launchpad.net/bugs/1847250

We expect this firmware update could be released with 19.10

[Impact]
We have a couple of Dell machines, after installing the system, it
will hang randomly, and this issue was reported by factory, they met
this issue a couple of times. Then we tried to reproduce this issue,
finally reproduced it.

[Fix]
Intel debugged this issue as well, and they provided 4 kernel patches
and a new firmware, we tested them, they really can fix the issue.
And the patches were sent the SRU already, now it is time to update
firmware.

[Test Case]
Install the system repeatedly and there is no hang issue anymore.

[Regression Risk]
Low, Intel told us there is no ABI change for the firmware, so
it is safe to run this firmware both with the old driver (not applied
those 4 patches) and the new driver (applied those 4 patches).
