Staging: Add pristine upstream vt6656 driver sources to drivers/staging/vt6656.

Add pristine upstream vt6656 driver sources to drivers/staging/vt6656.  These
files were copied from the driver directory in the upstream source archive,
available here:

  http://www.viaarena.com/Driver/VT6656_Linux_src_v1.19_12_x86.zip

After copying, trailing whitespace was stripped.  This is GPL-licensed code.
