Convert DRIVER_ATTR macros to DRIVER_ATTR_RO requested by
Greg KH. Also switched to using scnprintf instead of snprintf
per Documentation/filesystems/sysfs.txt.

Suggested-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Signed-off-by: Shane Seymour <shane.seymour@hp.com>

This patch was implemented on top of the previous patch to
convert to using driver attr groups.

Changes from v1:
- switched to scnprintf from sprintf after feedback from Sergey
Senozhatsky.
