arm64: Add support for using ARM Trusted Firmware as secure monitor
This patch adds support for integrating the runtime-resident component of ARM Trusted Firmware (github.com/ARM-software/arm-trusted-firmware) called BL31. It expects the ARM TF source tree to be checked out under $(top)/3rdparty/arm-trusted-firmware, which will be set up in a later patch. Also include optional support for VBOOT2 verification (pretty hacky for now, since CBFSv1 is just around the corner and will make all this so much better). BRANCH=None BUG=None TEST=Booted Oak with ARM TF and working PSCI (with additional platform patches).
