Bug description:
[Impact]
Certain Rembrandt designs use LPDDR memory and current firmware in
linux-firmware package in Focal and Jammy has a failure resuming from s0i3 on
DC power with it.
Some sample designs affected by the failure are Thinkpad X13, Z13,
Z16.
This failure doesn't affect resume with AC power or designs without
LPDDR memory.
[Fix]
Upgrade yellow carp DMCUB firmware binary.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/commit/?id=4458bb4185b6d6e1f5c586fcf4b8cf6f5d3c8e24
[Test]
Verify suspend/resume works.
Verify that externally plugged displays haven't regressed.
[Where problems could occur]
Firmware is only loaded to Rembrandt designs. Regressions would be tied to
those platforms.
