misc: Add a backward compatibility layer for Axxia MTC

commit a2cb6160 from
https://github.com/axxia/linux-yocto.git

 v5.10/standard/axxia-dev/base.

Some older code expects the Axxia MTC driver API that used
the older 'LSI' names. This commit provides those names but
calls the updated API in include/linux/axxia-mtc.h.
