ACPI: Schedule /proc/acpi/event for removal
Schedule /proc/acpi/event for removal in 6 months. Re-name acpi_bus_generate_event() to acpi_bus_generate_proc_event() to make sure there is no confusion that it is for /proc/acpi/event only. Add CONFIG_ACPI_PROC_EVENT to allow removal of /proc/acpi/event. There is no functional change if CONFIG_ACPI_PROC_EVENT=y Signed-off-by: Len Brown <len.brown@intel.com>
