soc/intel/common/gpio: fix gpi_status_get() 

A pad number is passed into gpi_status_get() to determine if its
associated bit is set from a generated event. However, the
implementation wasn't taking into account the gpi_status_offset
which dictates the starting offset for each community. Additionally,
the max_pads_per_group field is per community as well -- not global.
Fix the code to properly take into account the community's
gpi_status_offset as well as the max_pads_per_group.
