soc/intel/common/block/gpio: Change group offset calculation
Add group information for each gpio community and use it to
calculate offset of a pad within its group. Original implementation
assumed that the number of gpios in each group is same but that lead to
a bug for cnl since numbers differ for each group.
BUG=b:69616750
TEST=Need to test again on SKL,CNL,APL,GLK
