Michal Lenc a1f5fd4e72 icjx: use iC-JX interrupt config instead of the general one 
There might be multiple expanders, one with interrupt used and other
without. This commit fixes initial incorrect interrupt design by
introducing ICJX_INT_ENABLE config option.

Also fixes naming of ICJX_MULTIPLE option.

EMC-caused toggling of output pins.
