ok, i was thinking this was something we added (since we have "ADVxxx" parts)

meh, they're all wrong imo then :p.  they're shifting the address to
accommodate datasheets that incorrectly specify the i2c "address" with
the read/write as bit 0.  but it's fine for this driver to do that if
it's the standard that the rest of the v4l code has adopted.
