rG649f21d4d7a8: LinuxKPI: add (skeleton) functions to make drivers compile
rG75388b9ca5e5: LinuxKPI: add (skeleton) functions to make drivers compile

Summary

Add more functions to netdevice.h (netif_napi_add_tx() being the only
one implemented) and add platform_device.h and netlink.h in order to
make driver code compile.
The skeleton functions are used only in very limited scope and not at
all in our usage so far but add (invasive) #ifdef if removed.
Add pr_debug() calls to each of them in order to log a TODO (if DEBUG
compiled in) and someone should hit them in the future.

MFC after: 3 days

Test Plan

In the local dev tree I actually use more prominent logging
or even panic on them and have not come across them.
