Use more standard prototypes for i2c_use_client() and
i2c_release_client(). The former now returns a pointer to the client,
and the latter no longer returns anything. This matches what all other
subsystems do.

I2C adapter drivers are supposed to handle retries on nack by themselves
if they do, so there's no point in setting .retries if they don't.
As this retry mechanism is going away (at least in its current form),
clean this up now so that we don't get build failures later.

Update comments and logging on return path for byte writes. NAK is
an error, to be reported or optionally ignored. Timeouts are always
errors. Lost arbitration is not currently handled, so don't even list
it as an option in the error message.
Don't return bogus EFAULT code for inappropriate NAK; EIO is better,
there is no bad userspace address in question.

Use numbered adapter registration to always have the same hardware bus
show up at the same number.
PWRficient 1682M has three buses, they are all on the same PCI device but
different functions. So do the simple thing and register them based on
function number. Future products, if having a different number of busses,
are expected to have similar behaviour w.r.t. device/function layout.
