[PATCH v2 03/20] hw/arm: bananapi_m2u: Store boot info in the machine state

[Bin Meng <bin.meng@processmission.com>]

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 Bpim2uMachineState 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")
