Logan Gunthorpe 5d8e1881f4 switchtec: Add sysfs attributes to the Switchtec driver
Add a few read-only sysfs attributes which provide some device information
that is exposed from the devices, primarily component and device names and
versions.

These are documented in Documentation/ABI/testing/sysfs-class-switchtec.
