ACPICA: Remove some code duplication from acpi_ev_address_space_dispatch

ACPICA commit 383f50ff8cb7424ca16a6c0234f103b41d4a783e The handling of the space_id == ACPI_ADR_SPACE_GSBUS and space_id == ACPI_ADR_SPACE_GPIO cases is almost identical, fold the 2 cases into 1 to remove some code duplication.
