    hw/arm: musicpal: Store boot info in the machine state

    arm_load_kernel() keeps a pointer to the boot info struct for the
    lifetime of the VM, so the struct logically belongs to the machine
    rather than to a file scoped static object.

    Move it into a new MusicPalMachineState and register the machine type
    explicitly instead of through the DEFINE_MACHINE_ARM macro.

    As in the xlnx-zcu102 and raspi machines, the boot info belongs to
    the machine rather than to a static object:

    4d1ac883a7 ("hw/arm: xlnx-zcu102: Move arm_boot_info into XlnxZCU102")
    0f15c6e338 ("hw/arm/raspi: Move arm_boot_info structure to RaspiMachineState")
