The direct firmware class API support original relied
on the destination address to determine which file operations
to link to the data binary file. Since the 4.4 kernel version,
this was changed to an attribute group.
Fix this by adding a direct firmware API attribute group and

flask.h was included in the above file. This is autogenerated header
which gets produced during compilation of selinux. This causes issues
for other module (PFK) which includes objsec.h and compiles after
selinux. Since removal of the above headers does not break compilation,
they seem to be redundant and can be removed.
