This patch completely rewrites VIASave and VIARestore functions

Completely rewrites VIASave and VIARestore functions inside via_vgahw.c.
It now saves and restores virtually all VIA Technologies defined extended VGA
The previous code did not save all extended VGA registers, so many registers
were not being restored at all.
That being said, Chrome 9 HD HDMI or DisplayPort registers are not being saved
or restored since they cannot be accessed via VGA I/O ports.
    The compiled device driver was tested on the following computer.

 - Epic 1314 laptop (MSI VR321 laptop equivalent, VN896 chipset)
   with Lubuntu 12.04 i386
