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).
