s390/cio: Export information about Endpoint-Security Capability
Add a new sysfs attribute 'esc' per chpid. This new attribute exports
the Endpoint-Security-Capability byte of channel-path description block,
which could be 0-None, 1-Authentication, 2 and 3-Encryption.
For example:
$ cat /sys/devices/css0/chp0.34/esc
0
