Yes, really. Pity I didn't have the time to review the at24-to-nvmem
changes as much as I hoped for. But it will be good in the end.

I am really thankful that you made the effort to convert this hardly
used memory_accessor thing and convert it into the more widely used
nvmem mechanism. And clean up the unneeded bits afterwards. Always nice
to see such attitude :)
