[PATCH] docs/system/target-avr: Improve the AVR docs and add to MAINTAINERS

[Thomas Huth <huth@tuxfamily.org>]

The examples look nicer when using "::" code blocks.
Also mention that "-d in_asm" only outputs instructions that have not
been translated by the JIT layer yet.
And while we're at it, also add the AVR doc file to the MAINTAINERS file.

 Following are examples of possible usages, assuming demo.elf is compiled for
 AVR cpu
 
- - Continuous non interrupted execution:
-   ``qemu-system-avr -machine mega2560 -bios demo.elf``

- - Continuous non interrupted execution with serial output into telnet window:
-   ``qemu-system-avr -machine mega2560 -bios demo.elf -serial
-   tcp::5678,server,nowait -nographic``
-   and then in another shell
-   ``telnet localhost 5678``

- - Debugging wit GDB debugger:
-   ``qemu-system-avr -machine mega2560 -bios demo.elf -s -S``
-   and then in another shell
-   ``avr-gdb demo.elf``

-   ``target remote :1234``
