[RFC PATCH 2/4] hw/arm/raspi: Replace TARGET_AARCH64 by legacy_binary_is_64bit()

[Philippe Mathieu-Daudé]

For legacy ARM binaries, legacy_binary_is_64bit() is
equivalent of the compile time TARGET_AARCH64 definition.

Use it as TypeInfo::registerable() callback to dynamically
add Aarch64 specific types in qemu-system-aarch64 binary,
removing the need of TARGET_AARCH64 #ifdef'ry.
