via-camera upstream test results

Hi Jon,

Testing with clean linux-next as of today. 2 via-camera issues:

1. Approx 13 "VIA DMA timeout!" messages are printed every second

2. If you start a capture with "gst-launch v4l2src ! xvimagesink" then
change to a VT console then back to X, the display stops updating
properly - it seems to have locked itself onto a few frames from
before the VT switch happened, and plays them in an endless loop
Also happens with "gst-launch v4l2src ! ffmpegcolorspace ! ximagesink"

To get it working you just have to make 1 change to via-core.c :
-       [VIA_PORT_2C]   = { VIA_PORT_GPIO, VIA_MODE_I2C, VIASR, 0x2c },
+       [VIA_PORT_2C]   = { VIA_PORT_GPIO, VIA_MODE_GPIO, VIASR, 0x2c },

Would appreciate your help on these when you have some time.
