warp7 : run sec_init for CAAM RNGlinaro-20180124-001
This patch adds a sec_init call into board_init. Doing so in conjunction
with the patch "drivers/crypto/fsl: assign job-rings to non-TrustZone"
enables use of the CAAM in Linux.
u-boot will initialise the RNG and assign ownership of the job-ring
registers to a non-TrustZone context. Linux then simply has to detect or be
told to skip RNG initialisation.
