warp7: Add warp7 platform to the build
Previous changes in this series made the necessary driver additions and updates. With those changes in-place we can add the platform.mk and bl2_el3_setup.c to drive the boot process. After this commit its possible to build a fully-functional TF-A for the WaRP7 and boot from the BootROM to the Linux command prompt in secure or non-secure mode.
