backports: Remove unused parts

This removes parts which were only used by subsystems which are not
included in backports any more, for example media, bluetooth and
Ethernet.
The patches which are removed in this commit are not applied to the
kernel tree anyway with the default configuration because non of the
files get copied. The freezer, media, regulator and sound parts were
only used by the already removed media drivers. The flow dissector file
is not copied any more.
