Adds bl2 with FIP to the build required for mbed Linux booting where we do: BootROM -> SPL -> BL2 -> OPTEE -> u-boot If NEED_BL2 is specified then BL2 will be built and BL31 will have its address range modified upwards to accommodate. BL31 must be loaded from a FIP in this case. If NEED_BL2 is not specified then the current BL31 boot flow is unaffected and u-boot SPL will load and execute BL31 directly.
