fsl_sec: Add hardware accelerated SHA256 and SHA1

Browse Source 
SHA-256 and SHA-1 accelerated using SEC hardware in Freescale SoC's
The driver for SEC (CAAM) IP is based on linux drivers/crypto/caam.
The platforms needto add the MACRO CONFIG_FSL_CAAM inorder to
enable initialization of this hardware IP.
