This driver doesn't registers itself automatically, as it needs to
be provided with platform specific configuration, provided by some
board driver setup code.
Didn't implement oftree probing yet, as it's rarely found on x86.

Add slimSSS node to DT and crypto AES support for Exynos5433. Tested on
Exynos5433 board with crypto run-time self tests and with tcrypt with
command insmod tcrypt.ko mode=500 sec=1
Changes since v3:
- moved bindings documentation out from samsung-sss.txt into separate file
samsung-slimsss.txt
Add DT node for SlimSSS (aka Slim SecuritySubSystem) in Exynos5433 SoC.
The users can use compatibility "samsung,exynos5433-slim-sss".
