Change ArmJunoDxe to be compatible with the new DtPlatformDxe driver,
which simply selects one of three embedded DTB binaries based on the
current hardware. It also introduces a config screen in the UEFI setup
menu that allows either ACPI or DT to be selected (but not both)

For this module, it simply means we remove all FDT handling, given that
this is now the job of another module.
