FWIW, the reason it's addmap{0,1} is that the datasheet has documents
ADDMAP=0 and the first bank of registers and ADDMAP=1 as the second bank
of registers. I adopted that to match the docs for the part.

I guess we could do i2c and i2c_sec, I'll just have to put a comment
correlating it to the h/w. Calling it 'slv' implies something else
so we should avoid that here. The notion of a "secondary" i2c device
is completely a Linux I2C subsystem fabrication which wouldn't exist
if it allowed multiple slave addresses per device. From a h/w
perspective there is really no primary and secondary relationship.

I'm fine with i2c/i2c_sec or addrmap0/1 and I will just comment to
correlate with the datasheet..pick one.
