This allows a .tar.gz file that is normally downloaded from the server to be
checked directly into a test branch. Now when the firmware is being installed,
it can be extracted from any present .tar.gz. Again, this is primarily to
simplify testing.
A nice side effect is that when going from a newer version to an older version,
any stale .bin files in the firmware directory will not be installed into
/lib/firmware, but instead the bin file from the *versioned* .tar.gz will always
be installed. This should reduce problems where you have to run "make
dist-clean" when reverting to an older version that has a firmware change.
