[PATCH] arm64: defconfig: drop four symbols that no longer exist

[PATCH] arm64: defconfig: drop four symbols that no longer exist

[TAKANO Mitsuhiro]

None of these symbols exists any more, so the lines look like options that
can still be chosen:

  NFS_V4_1                  folded into NFS_V4 (7537db24806f, 2025-12-04)
  SLIM_QCOM_CTRL            driver removed     (7cbba32a2d62, 2025-09-12)
  NET_VENDOR_PACKET_ENGINES vendor removed     (aec3202247b4, 2026-04-22)
  SCHED_DEBUG               option removed     (b52173065e0a, 2025-03-17)

Three of the lines went stale when their symbol disappeared.  The Ethernet
line was added by commit 32379ad4060b ("arm64: defconfig: Drop unused
Ethernet vendors") on 2026-04-29, a week after the packetengines vendor
directory had been removed, so it was stale from the start.

Scanning every Kconfig definition in the tree leaves no other stale line
in this file.  Similar leftovers remain in other architectures'
defconfigs; those are not touched here.

Mikko Rapeli sent a patch for the SLIM_QCOM_CTRL line in December 2025,
and Vincent Mailhol's "configs: cleanup obsolete or incorrect assignments"
series carried the NFS_V4_1 and SLIM_QCOM_CTRL lines in March 2026; both
submissions are still unmerged.  This patch covers all four lines and
would supersede those hunks; I am happy to drop the corresponding hunk if
either author would rather keep their own.

Tested as configuration text only: "make ARCH=arm64 defconfig" on v7.4-rc2
with and without this change gives a byte-identical .config, and "make
savedefconfig" emits none of the four lines.  No kernel was built or
booted from this change.

The change and the changelog text were produced with an AI coding
assistant (Hermes Agent, model deepseek-v4.1-flash) working from the tree
and the git history.  I reviewed the diff and the reasoning, and I am
responsible for the submission.

Nothing below is suitable for git commit, drop.

This goes to changelog, not commit msg, so under ---.

Not suitable for git log.
