In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

This patch fixes the following warnings:

drivers/gpu/drm/via/via_dmablit.c:179:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
drivers/gpu/drm/via/via_dmablit.c:185:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
drivers/gpu/drm/via/via_dmablit.c:187:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
drivers/gpu/drm/via/via_dmablit.c:195:3: warning: this statement may fall through [-Wimplicit-fallthrough=]

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enabling
-Wimplicit-fallthrough.

History
Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
