[PATCH v2] ARM: exynos_defconfig: Enable CONFIG_LOCKUP_DETECTOR

[Anand Moon]

Enable CONFIG_LOCKUP_DETECTOR to validate kernel locks state for exynos SOC.

Enabling CONFIG_LOCKUP_DETECTOR help validator tracks the 'state' of lock-classes,
and it tracks dependencies between different lock-classes.
The validator maintains a rolling proof that the state and
the dependencies are correct.

Changes since v2:
 * Made commit message more clear
 * Corrected grammer in code comment

Tested on Exynos5422 ODROID XU3 board.
