Subject: [PATCH 4.19 17/34] Kconfig.debug: drop selecting non-existing HARDLOCKUP_DETECTOR_ARCH

From: Lukas Bulwahn <lukas.bulwahn@...il.com>

[ Upstream commit 6fe26259b4884b657cbc233fb9cdade9d704976e ]

Commit 05a4a9527931 ("kernel/watchdog: split up config options") adds a
new config HARDLOCKUP_DETECTOR, which selects the non-existing config
HARDLOCKUP_DETECTOR_ARCH.

Hence, ./scripts/checkkconfigsymbols.py warns:

HARDLOCKUP_DETECTOR_ARCH Referencing files: lib/Kconfig.debug

Simply drop selecting the non-existing HARDLOCKUP_DETECTOR_ARCH.
