From: Ye Li <ye.li at nxp.com>

The imx8mm has changed the address of rvt_hab, use new address for imx8mm.

The authentication procedure is same as imx8mq. In u-boot, the authentication
uses SIP call to trap ATF to run HAB authenticate.

Users need to add CONFIG_SECURE_BOOT=y to defconfig to enable the feature.
