pinctrl: sunrisepoint: Add missing Interrupt Status register offset

commit 9608ea6c6613ced75b2c41703d99f44e6f8849f1 upstream.

Commit 179e5a6114cc ("pinctrl: intel: Remove default Interrupt Status
offset") removes default interrupt status offset of GPIO controllers,
with previous commits explicitly providing the previously default
offsets. However, the is_offset value in SPTH_COMMUNITY is missing,
preventing related irq from being properly detected and handled.
