No idea why this driver is using a char device node, statically
allocated, with no dynamic allocation or hook up with devtmpfs, along
with a reserverd major number, for "special" operations, not all of
which ever were implemented.

So just rip it out, as no one must be using it because no modern system
will ever actually create the /dev/ node it needs.

This file has a HUGE debugging sysfs file that spews out a lot of
information all at once, which violates the one-value-per-file rule for
sysfs.  If this is really needed, it should go into debugfs, but given
the age of this driver, I strongly doubt anyone is using it anymore.

So just remove the file entirely, it was never documented, so obviously,
no one actually needed it :)

If we assign 'epnum' during the declaration we can also avoid "ISO
C90 forbids mixed declarations" issues.  So it does looks like we
can have our cake and eat it in this scenario.

mux-agent does not have USB4 specific message, but it can be
put into the TBT3 alternate mode also with USB4. That is OK
