Add support for EMK TOP7000 CPU module

Specifics:

1) create subdir board/emk/top7000 and files in it
2) create include/configs/top7000.h
3) update board/emk/common/vpd.c
4) add call to misc_init_r() to arch/avr32/lib/board.c
5) create arch/avr32/include/asm/unaligned.h to
   fix zlib.c compilation problem
6) update Makefile, MAINTAINERS, MAKEALL

Signed-off-by: Reinhard Meyer <info@emk-elektronik.de>
