Haren Myneni 8c099490fd crypto/nx: Add sysfs interface to export NX capabilities

Export NX-GZIP capabilities to usrespace in sysfs
/sys/devices/vio/ibm,compression-v1/nx_gzip_caps directory.
These are queried by userspace accelerator libraries to set
minimum length heuristics and maximum limits on request sizes.

NX-GZIP capabilities:
min_compress_len  /*Recommended minimum compress length in bytes*/
min_decompress_len /*Recommended minimum decompress length in bytes*/
req_max_processed_len /* Maximum number of bytes processed in one
			request */

NX will return RMA_Reject if the request buffer size is greater
than req_max_processed_len.
