hw/arm: npcm8xx: 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 inside
npcm8xx_load_kernel().
Let the caller own the boot info: the board stores it in its
NPCM8xxMachine and passes it to npcm8xx_load_kernel(), which only
fills in the SoC specific values.
As in the xlnx-zcu102 and raspi machines, the boot info belongs to
the machine rather than to a static object:

0f15c6e338 ("hw/arm/raspi: Move arm_boot_info structure to RaspiMachineState")
