[PATCH] ARM: exynos_defconfig: disable CONFIG_EXYNOS5420_MCPM; not stable

[khilman@kernel.org (Kevin Hilman)]

From: Kevin Hilman <khilman@linaro.org>

The option CONFIG_EXYNOS5420_MCPM is causing imprecise external aborts
during boot testing, causing various userspace startup failures.

Disable until it has gotten more testing.

This has been reported by a few people[1], but not investigated or fixed, so it's
time to disable this feature until it can be fixed.
