[U-Boot] [PATCH 2/4 v3] Exynos: config: Enable ACE HW for SHA 256 for Exynos

[Akshay Saraswat]

This enables SHA 256 for exynos.

Tested with command "hash sha256 0x40008000 0x2B 0x40009000".
Used mm and md to write a standard string to memory location
0x40008000 and ran the above command to verify the output.
