GPIO LV (low voltage)/MV (medium voltage) subtypes have different
features and register mappings than 4CH/8CH subtypes. Add support
for LV and MV subtypes.

defines for strings? That's really pointless. I'd prefer you drop using
them than add more.

Thanks for the suggestion, I will remove these string definitions in next patch.
Does other part look good? I would post a new patch if no other comments.
