S3 suspend failing for RX6700XT

Symptoms:

you try a suspend-to-rum (ACPI-S3) and the system simply doesn't do it, instead
some devices (hdd) wake up again after a few seconds but the system is "in the
limbo", semi-dead, only sync and reboot with magic-sysrq s/u/b works. See
attachment.


Good/bad versions:

Kernels v6.16.x were fine
Kernels v6.17.0-rc<something> started failing


Results of bi-secting: see below.

I didn't want to start bitching around but seriously, for me this kind of
suspend-resume-freeze-fu*up-in-a-RELEASED-kernel has happened a couple of times
now. Isn't there any kind of quality control in AMD's integration team for the
"older" RX 6xxx generation?

    drm/amdgpu: Wait for bootloader after PSPv11 reset

    Some PSPv11 SOCs take a longer time for PSP based mode-1 reset. Instead
    of checking for C2PMSG_33 status, add the callback wait_for_bootloader.
    Wait for bootloader to be back to steady state is already part of the
    generic mode-1 reset flow. Increase the retry count for bootloader wait
    and also fix the mask to prevent fake pass.
