Yuan Liu dc05ffffaa dm: uart: fix acrn-dm crash issue ...

This patch resolves acrn-dm crash issue when acrnd boots up the acrn-dm.
The rootcause is mevent_enable and mevent_disable have NULL pointer as
its parameter if uart backend is not tty capable, so add check code for
the uart backend before invoking mevent_enable and mevent_disable.

The issue can be reproduced when acrnd boots up the acrn-dm.
