Some low memory systems with complex peripherals cannot afford to have
the relatively large firmware images taking up valuable memory during
suspend and resume. Change the internal implementation of
firmware_class to disallow caching based on a configurable option. In
the near future, variants of request_firmware will take advantage of
this feature.
