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.
