[PATCH 17/27] hw/avr: Include missing 'system/memory.h' header

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

"system/memory.h" header is indirectly pulled by "hw/sysbus.h".
Include it explicitly to avoid when refactoring the latter:

  In file included from ../../hw/misc/avr_power.c:26:
  include/hw/misc/avr_power.h:40:18: error: field has incomplete type 'MemoryRegion' (aka 'struct MemoryRegion')
     40 |     MemoryRegion iomem;
        |                  ^
  In file included from ../../hw/timer/avr_timer16.c:39:
  include/hw/timer/avr_timer16.h:51:18: error: field has incomplete type 'MemoryRegion' (aka 'struct MemoryRegion')
     51 |     MemoryRegion iomem;
        |                  ^
  In file included from ../../hw/char/avr_usart.c:23:
  include/hw/char/avr_usart.h:67:18: error: field has incomplete type 'MemoryRegion' (aka 'struct MemoryRegion')
     67 |     MemoryRegion mmio;
        |                  ^
  include/qemu/typedefs.h:68:16: note: forward declaration of 'struct MemoryRegion'
     68 | typedef struct MemoryRegion MemoryRegion;
        |                ^
