Add empty weak assembler function armv8_switch_to_el2_prep() which is jumped to just before U-Boot determines which EL it is running in and decides which path to take to boot the Linux kernel. Add IH_TYPE_TFA_BL31 into supported images type, to allow implementation of board specific U_BOOT_FIT_LOADABLE_HANDLER(IH_TYPE_TFA_BL31, ...) TFA BL31 loadable handler for fitImages.
