Defconfig (exynos and multi_v7) changes for Exynos based boards for v4.6:
1. exynos defconfig:
   a. Enable NEON and accelerated crypto,
   b. Enable s5p-secss driver (Security SubSystem block for accelerating
      some cryptographic operations),
2. exynos and multi_v7: Remove MAX77802 RTC Kconfig because the driver
   was combined into existing rtc-max77686 driver. This depends on changes
   from RTC tree.
