Philippe Mathieu-Daudé 74fb2f4f4c hw/avr: Realize AVRCPU qdev object using qdev_realize()
TYPE_AVR_CPU inherits TYPE_CPU, which itself inherits TYPE_DEVICE.
TYPE_DEVICE instances are realized using qdev_realize(), we don't
need to access QOM internal values.

Frederic Konrad 6cd04a88fa hw/avr/atmega.c: use the avr51 cpu for atmega1280
According to the as documentation:
 (https://sourceware.org/binutils/docs-2.36/as/AVR-Options.html)

"Instruction set avr51 is for the enhanced AVR core with exactly 128K
 program memory space (MCU types: atmega128, atmega128a, atmega1280,
 atmega1281, atmega1284, atmega1284p, atmega128rfa1, atmega128rfr2,
 atmega1284rfr2, at90can128, at90usb1286, at90usb1287, m3000)."

But when compiling a program for atmega1280 or avr51 and trying to execute
it:

$ cat > test.S << EOF
> loop:
>     rjmp loop
> EOF
$ avr-gcc -nostdlib -nostartfiles -mmcu=atmega1280 test.S -o test.elf
$ qemu-system-avr -serial mon:stdio -nographic -no-reboot -M mega \
                  -bios test.elf
qemu-system-avr: Current machine: Arduino Mega (ATmega1280) with 'avr6' CPU
qemu-system-avr: ELF image 'test.elf' is for 'avr51' CPU

So this fixes the atmega1280 class to use an avr51 CPU.

Eduardo Habkost db1015e92e Move QOM typedefs and add missing includes
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary
