UP² Celeron version (not the Atom one) has no console

[tbursztyka]

Describe the bug
UP² Celeron either does not boot or at least lost its console output
(the early console already, since the boot banner is not even printed out)

To Reproduce
Use samples/hello_world either on EFI or Grub

Expected behavior
Zephyr boot banner and hello world being printed out.

Impact
I use this board extensively and that is blocking my work atm

Environment (please complete the following information):

• OS: (e.g. Linux, MacOS, Windows)
• Toolchain:Zephyr SDK 12.2
• Commit 51c34bb

Additional context
I ran a git bisect and it is still the commit 5c47bbc

I have no idea why this commit affects Apollo Lake Celeron version and not the Atom one.

@tbursztyka this might because of a rebasing mistake in #31618

Try removing the explicit KERNEL_VM_SIZE from defconfig and see if it helps

@jhedberg yep that's the issue, thanks for noticing this

So it was not only a celeron version issue (I though that master was working for up2 and as it did not with mine...).
Closing, #31703 is fixing it.
