This fixes the following Linux kernel error message on the host:
usb 1-1: config 2 has 2 interfaces, different from the descriptor's value: 3

Initially it was a good choice to keep the LIU driver in the host
software (easier debugging/changes). However, we never really needed it
to do anything but initialization of the LIU.
So in order to avoid having to teach osmo-e1d or other software the
details about the LIU initialization, let's do this from the firmware
*if* the e1d compatible USB configuration is used.
Closes: OS#5733

This adds a second USB configuration to the e1-tracer firmware. This
configuration is closer to the USB configuration of an icE1usb and hence
paves the way for using osmo-e1d with the tracer.
The main conceptual difference between the existing "legacy"
configuration and this new "e1d compatible" configuration is to have two
USB interfaces, one for each direction of the traced E1 interface. Each
interface has its own separate two altsettings, one for the disabled
and one for the enabled state.
Unmodified osmo-e1d will not work straight away with this, as it expects
ISO OUT and ISU Feedback endpoints, which a pure rx-only tracing device
of course doesn't have.

Let's split the starting and stopping between the two channels.
This is a preparation for a future e1d-compatible mode where each
channel (direction) has its own USB interface and hence must be
individually started/stopped.

Let's explicitly specify the VID/PID of the e1-tracer in the dfu-util
invocation 'make dfuprog' to avoid accidentially programming other
attached dfu capable devices.

Those were low level debug meant to be temporary and somehow ended
up committed.

This resembles what we do for other firmware targets, such as simtrace2,
osmo-ccid-firmware, etc.
As we have multiple different firmware, hardware, gateware projects in
this repository, and they each may have separate tags, we now require
that there are project specific tags. So for example, tags with a
prefix of icE1usb-fw for the firmware versions.
symlinks for easy use by scripts etc. are generated, always pointing to
the last-built versioned filename.

This was broken when moving the design to non-hacked multi channel
E1.

This was never used and doesn't really belong here, this was just
an example descriptor in the original firmware this is based on.

This is a remanence of old firmware of the icepick on which that
design is based on.

The documentation always had the rRX tick in the LSB which
is consistent with having the RX units before TX.
They can be read as 16 bit value anyway so there isn't any
performance impact.

Some more code could probably be unified with the "normal" usb E1 adapter
to both reduce code duplication but also offer 'sniff' function to the
E1 adapter.
