V560tu/v540tu/nv4x_adl/ns50 needed staging fixups

[tlaurion]

input for #1846, taking missing commits + adaptations from #1871 so we have builds from CI to test and report on @mkopec

Not important, but CircleCI's v540tu/v650tu should depend on x230-hotp-maximized not n4x_adl. Gain in time is minimal reusing nv4x_adl build cache; important here is to reuse crosggc buildstack cached from x230-hotp-maximized, outside of that gains in compilation time is minimal at the cost of passing another unneeded layer of workspace cache for now, since since not reusing the same kernel version anyway? Let's optimize later not now, but note to myself. if we keep different kernel version, this might help otherwise its CI waiting time for nothing?

@mkopec kernel version still needs to be reviewed as needed or not on a v560tu that boots [efifb related, linux version not proven to be necessary as of now for efifb] (waiting for a build that doesn't cause bootloop on my side)

Also name string of v5640 is wrong will post other commit to rebuild when this one is done -> v560tu (board name good, just cosmetic)

@mkopec bootloop still with https://output.circle-artifacts.com/output/job/74d3cd5e-9da5-460d-9a29-ea34d475a781/artifacts/0/build/x86/novacustom-v560tu/heads-novacustom-v560tu-v0.2.0-2487-g133d1cd.rom

repro:

• flashed from stock rom, which I produced screenshot before, with --ifd -i bios -i me -i fd to flash into link provided rom from CI.
• Let it do its thing. 2 reboots without backlit whitish screen, black screen (Guess is memory training)
• 3rd reboot: whitish backlit. Each reboot is happening after 90s after power led lights up to reboot. Watchguard of some sort??
• if I press power button, powers off directly (coreboot behavior prior of linux kicking in)

Nothing I can report more here unfortunately. Can you replicate that this firmware works the same way on your side?
Haven't upgrade EC or anything else here. Whatever you have done to this test laptop that I haven't outside of flashing firmware with built rom would be appreciated to be communicated to me here. OR a test rom built with logs stored into rom to be backup and shared off channel to you or anything you see fit to unblock this. Let me know.

Managed to reproduce the freeze, it's freezing while attempting to disable ME:

[DEBUG]  me_state = 2
[DEBUG]  CMOS: me_state = 4294967295
[DEBUG]  ME needs to be disabled.
[ERROR]  HECI: not ready

Need to run git submodule update in side the coreboot dir

[mkopec]

@tlaurion I merged your patches into #1846 and added a fix for the ME disable freeze.

Closing this. Still having this python error, related to something weird in coreboot fork but this is not what this PR was about. Closing
