feat(versal2): add support for AMD Versal Gen 2 platform
New SoC is a78 based with gicv3 and uart over pl011. Communication
interfaces are similar to Versal NET platform. System starts with AMD PLM
firmware which loads TF-A(bl31) to memory, which is already configured, and
jumps to it. PLM also prepare handoff structure for TF-A with information
what components were load and flags which indicate which EL level SW should
be started.
