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
