ACPICA: New: acpi_get_gpe_device interface
This function maps an input GPE index to a GPE block device. Also Added acpi_current_gpe_count to track the current number of GPEs that are being managed by the ACPICA core (both FADT-based GPEs and the GPEs contained in GPE block devices.) Modify drivers/acpi/system.c to use these 2 new interfaces Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
