Add protocol object compare routines
Add routines pb_protocol_device_cmp() and pb_protocol_boot_option_cmp() to hide the implemention details of the device. The implementation of the id can be changed without effecting the users of it. Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
