MLK-23963 imx: mx6/7: Move configure_tzc380 to each SOC arch init

The commit "TEE-520 core: imx: Set TZASC region 0 to non-sec"
added configure_tzc380 function in imx_sec_init to set region 0 to
non-sec, however imx_sec_init is called only on SOCs which has CAAM.
For SOCs use DCP, like 6SLL, 6ULL/6ULZ, 6SL, this function does not
execute, and cause the trustzone won't be configured.
