It seems that lowlevel_init is indeed undefined when
CONFIG_SKIP_LOWLEVEL_INIT is defined.

The revised patch below fixes this and also removes the board
dependency from cpu/arm920t/at91rm9200/i2c.c - as far as I can
tell it is safe to allow two-byte addresses generally.

The following patches in my series are unaffected by this.

Cheers
Anders
