We need the ability to explicitly load only a specified firmware
version. As the firmware blob contains the version, we use
that to filter out the ones we don't want. The version encoded
into the firmware name is superfluous and we should allow user
to point into specific firmware through a symlink, and only do
filtering based on the version stamp included in the blob.
This allows user to conveniently point to a firmware blob and
still gives us the control of what we decided to run on.
This is partial revert of
