otp and cal loading logic, from 4.7-ish kernel

[Ben Greear]

Someone is trying to use my 4.7-ish driver on LEDE with a 9888 NIC.

It seems it loads the pre-cal data fine, but it fails to find the board file
in the board-2.bin logic.  I think this is because when pre-cal succeeds, then 'calret' is 0,
so we never get the board-ID, and then we cannot properly query the board-2.bin
file.

I don't think I've really messed much with this logic, but possibly I broke
something.

Any idea how this is supposed to work?

The logs look like this:
