iMX8M: Add support to enable CONFIG_IMX_HAB
Add some SOC level codes and build configurations to use HAB lib for
CONFIG_IMX_HAB (secure boot), like adding the SEC_CONFIG fuse, enable
fuse driver, CAAM clock function, and add CAAM secure RAM to MMU table.
The FSL_CAAM is temporally not enabled for iMX8M when CONFIG_IMX_HAB is set,
because we don't need the CAAM driver for SPL.
