Because the hardware changes from EVT to DVT, the CPLD firmware
reallocated the IOEXP pin mapping in DVT version.
I will add more description into the commit message in the next version.

I am not from the CPLD firmware team, I only know our CPLD team was
redesigning the entire struct which causes the huge changes of IOEXP
pins.

This is probably a different topic, I am curious about is it possible
to assign the linename in userspace?
In OpenBMC, there are many services that depend on GPIO linename, it
will be more flexible if I can assign the linename before service
starts.

Thanks,
Potin
