crypto: ccp - Add support for getting security attributes on some older systems

Browse Source 
Older systems will not populate the security attributes in the
capabilities register. The PSP on these systems, however, does have a
command to get the security attributes. Use this command during ccp
startup to populate the attributes if they're missing.
