ioat: add 'ioat' sysfs attributes
Export driver attributes for diagnostic purposes: 'ring_size': total number of descriptors available to the engine 'ring_active': number of descriptors in-flight 'capabilities': supported operation types for this channel 'version': Intel(R) QuickData specfication revision This also allows some chattiness to be removed from the driver startup as this information is now available via sysfs.
