When logging async events the scsi_id, wwpn, and node_name values
are used directly from the CRQ struct which are of type __be64. This
can be confusing to someone looking through the log on a LE system.

Treating as bit rot and removing the associated host config code.
The config attribute and its show function are left as not to break
userspace. The behavior remains the same returning nothing.

The root node of the OF device tree is exported as of_root. No need
to look up the root by path name. Instead just get a reference
directly via of_root.
