====================
fix and move definitions of MRP data structures

We unnecessarily included packet structures of MRP in a uAPI header.
Turns out that some of them were in fact broken due to lack of packing,
so let's take this chance to remove them completely. Leave it to user
space to create its own, correct definitions. Said structures are not
used in the user space <> kernel communication.
