This patch adds implementation of rand library based on hardware random number generator of security subsystem in Exynos SOC. This library includes: - srand() - used for seed hardware block - rand() - returns random number - rand_r() - the same as above with given seed which depends on CONFIG_EXYNOS_ACE_SHA and CONFIG_LIB_HW_RAND.
