secure_boot: enable chain of trust for PowerPC platforms
Chain of Trust is enabled for PowerPC platforms for Secure Boot.
CONFIG_BOARD_LATE_INIT is defined.
In board_late_init(), fsl_setenv_chain_of_trust() is called which
will perform the following:
- If boot mode is non-secure, return (No Change)
- If boot mode is secure, set the following environmet variables:
bootdelay = 0 (To disable Boot Prompt)
bootcmd = CONFIG_CHAIN_BOOT_CMD (Validate and execute Boot script)
