scd:p15: Prepare AODF parsing for other authentication types.
* scd/app-p15.c (auth_type_t): New. (struct aodf_object_s): Add field auth_type. (read_ef_aodf): Distinguish between pin and authkey types. Include the authtype in the verbose mode diags.
Note that the bulk of chnages are just indentation chnages. There
should be no functional change.
