arm64: zynqmp: Use DT header for firmware constants

Firmware contants do not fit the purpose of bindings because they are not
independent IDs for abstractions. They are more or less just contants which
better to wire via header with DT which is using it. That's why copy header
to platform folder (align macro) and use it locally.
