On enabling CONFIG_LOCKUP_DETECTOR the kernel to act as a watchdog
to detect hard and soft lockups. Enabling CONFIG_LOCKUP_DETECTOR
don't introduce much overhead on exyons SOC.
CONFIG_LOCKUP_DETECTOR is enabled on multi_v7_defconfig.
Changes since v3:
* Made commit message more clear
* Corrected difference between CONFIG_LOCKUP_DETECTOR and CONFIG_LOCKDEP.
Tested on Exynos5422 ODROID XU3 board.
