ACPICA: Events: Cleanup to move acpi_gbl_global_event_handler invocation out of acpi_...

ACPICA commit 04f25acdd4f655ae33f83de789bb5f4b7790171c

This patch follows acpi_ev_fixed_event_detect(), which invokes
acpi_gbl_global_event_handler instead of invoking it in
acpi_ev_fixed_event_dispatch(), moves acpi_gbl_global_event_handler from
acpi_ev_gpe_dispatch() to acpi_ev_gpe_detect(). This makes further cleanups
around acpi_ev_gpe_dispatch() simpler. Lv Zheng.
