viafb: introduce per output device power management
This patch moves common parts of dvi.c, lcd.c and vt1636.c to hw.c to start a per output device power management. There should be no runtime changes aside that this patch enables the proc interface to enable/disable devices when needed which greatly increases the chances that changes to the output device configuration will work. However the power management is not yet complete so it might fail on some configurations. As this area is quite complex and touches undocumented things there is a slight chance of regressions.
