MLK-19064 imx8qm: Add secure boot environment
Add the secure boot relevant environment variables to ARM2 and MEK.
When CONFIG_AHAB_BOOT is enabled, we will switch to boot flow:
1. Load the signed OS container to address 0x88000000
2. Using auth_cntr to authenticate the OS container. It will load the
kernel and FDT to destination addresses.
3. Using booti to boot kernel.
