Most ARM board files declare their struct arm_boot_info as a static
object at file scope (or, occasionally, as a function-local static
inside the machine init function). arm_load_kernel() stashes a pointer
to that struct in every CPU and dereferences it from do_cpu_reset() on
each reset, so the boot info conceptually belongs to the machine for the
lifetime of the VM, not to a static object whose ownership is left
implicit.

This is a longstanding leftover pattern: modern machines such as virt,
raspi and xlnx-zcu102 already keep the boot info in their MachineState
subclass. This series converts the remaining machines that still use
a static object, moving the struct into their machine state so that its
lifetime and ownership match how arm_load_kernel() actually uses it.
