As things stand currently, there is only one PowerPC platform that enables the options for CHAIN_OF_TRUST. From the board header files, remove a number of never-set options. Remove board specific values from arch/powerpc/include/asm/fsl_secure_boot.h as well. Rework include/config_fsl_chain_trust.h to not abuse the CONFIG namespace for constructing CHAIN_BOOT_CMD. Migrate all of the configurable addresses to Kconfig. If any platforms are re-introduced with secure boot support, everything required should still be here, but now in Kconfig, or requires migration of an option to Kconfig.
