Great! Note that the bug in the ->send_ccc_cmd() path should be fixed,
but you might have issues with i2c transfers as msg->buf is not
guaranteed to be aligned on 32-bit.

Don't know if you've followed the discussion with Arnd, but it seems
some (most?) archs are making sure writesl()/readsl() work for
unaligned bufs. Maybe we should fix that for ARC. The other solution is
to use i2c_get_dma_safe_msg_buf() to get something aligned on a
cache-line and by extension aligned on 32bits.
