treewide: drop CONFIG_EMBEDDED

There is only one Kconfig user of CONFIG_EMBEDDED and it can be switched
to EXPERT or "if !ARCH_MULTIPLATFORM" (suggested by Arnd).

arch/*/configs/*defconfig: Replace AUTOFS4_FS by AUTOFS_FS

Commit a2225d931f75 ("autofs: remove left-over autofs4 stubs")
promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS
within a couple of releases, but five years later this still has not
happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs.

Get rid of it mechanically:

git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' |
xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/'

Also just remove the AUTOFS4_FS config option stub. Anybody who hasn't
regenerated their config file in the last five years will need to just
get the new name right when they do.

ARM: defconfig: reorder defconfig files

The debug-info and can subystem options have moved around in the
'savedefconfig' output, so fix these up to reduce the clutter
from the savedefconfig command.

ARM: defconfig: address renamed CONFIG_DEBUG_INFO=y

CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the
explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT,
DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5.

This was actually not what I had in mind when I suggested making
it a 'choice' statement, but it's too late to change again now,
and the Kconfig logic is more sensible in the new form.

Change any defconfig file that had CONFIG_DEBUG_INFO enabled
but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain
default.

The default is always 0x0 after commit 39c3e304567a ("ARM: 8984/1:

defconfig file that has these two lines can now drop them to reduce

ARM: refresh defconfig files

A lot of Kconfig options have changed over the years, and we tend
to not do a blind 'make defconfig' to refresh the files, to ensure
we catch options that should not have gone away.

I used some a bit of scripting to only rework the bits where an
option moved around in any of the defconfig files, without also
dropping any of the other lines, to make it clearer which options
we no longer have.

made default to 'n',
2. It is not recommended (help message: "This should not be used today
