- Add documentation for some known registers
- Add support for vga modes (320x240, 160x120) for sif sensors
- Remove F_RAW sensor flag raw mode should work on any sensor as its a bridge
   only thing and keeping the flag was becoming awkward.
- Fixup ov6650 and pas106 auto exposure window settings

This adds basic support for the Hauppauge Nova-TD-500 84xxx series.

A future patch will allow for one aerial input to supply both tuners.

With the current code, an aerial must be plugged into each antannae input
in order for both tuners to function.

Some DVB drivers are incorrectly assuming that the size of
i2c_adapter.name is I2C_NAME_SIZE.  Here's a fix.

Also change strncpy to strlcpy, as the former is error-prone (and was
indeed incorrectly used.)

1) Lower the hstart setting for all sensor by 1 so that we generate
   (compressed) BGGR data just like sn9c102 does (instead of GBRG data)
2) Add support for raw bayer output in the lowest resolutions (not enough
   bandwidth for higher resolutions), this should work with all sensors but
   to be sure only enable it for sensors where it has been tested.

the uncompressed size (seen with 0c45:6028), so make the buffers slightly

-the usb-id table caried several flags which were not usb-id specific but
 sensor specific, add a sensor_data array and move these flag there
-fr_h_sz was being abused to store and check which bridge was being used
 instead add a bridge member to the sd struct
-now that we have a sensor_data table use that to store pointers to
 init_sequences instead of using switch cases on sd->sensor

cx18: Simplify queue flush logic to prevent oops in cx18_flush_queues().
