media: dmx.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. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
