[PATCH v4 2/8] serial: sunzilog: Remove unnecessary volatile keyword

[Thierry Reding <thierry.reding@gmail.com>]

From: Thierry Reding <treding@nvidia.com>

The field annotated with volatile are all accessed through I/O accessors
so they don't need to be explicitly marked. The accessors will take care
of it.
