serial-dmm: Remove global sr_dev_driver *di alias

The global *di alias was used to keep track of the driver context.
It caused issues with trying to use several subdrivers at once, so
its use was obsoleted.

The correct context is preserved through different mechanisms, either
the *sdi pointer, or wrappers which pass the correct context.

The *di alias is no longer used, so remove it.
