bus: ti-sysc: Fix wrong offset for display subsystem reset quirk
Commit 7324a7a0d5e2 ("bus: ti-sysc: Implement display subsystem reset
quirk") added support for DSS reset, but is using dispc offset also for
DSS also registers as reported by Tomi Valkeinen <tomi.valkeinen@ti.com>.
Also, we're not using dispc_offset for dispc IRQSTATUS register so let's
fix that too.
