media: ca.h: split typedefs from structs

Using typedefs inside the Kernel is against CodingStyle, and
there's no good usage here.

Just like we did at frontend.h, at commit 0df289a209e0 ("[media] dvb:
Get rid of typedev usage for enums"), let's keep those typedefs only
to provide userspace backward compatibility.

No functional changes.
