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.
