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 Change-Id: I02ab1d878bc83d32222be074bd2db5e23adaf580 Signed-off-by: Bora Guvendik <bora.guvendik@intel.com> Reviewed-on: https://review.coreboot.org/22571 Reviewed-by: Lijian Zhao <lijian.zhao@intel.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>
