Staging: add the go7007 video driver 

Todo:
	- checkpatch.pl cleanups
	- sparse cleanups
	- lots of little modules, should be merged together
	  and added to the build.
	- testing?
	- handle churn in v4l layer.

Many thanks to Ross Cohen <rcohen@snurgle.org> for cleanup patches on
this driver.

/************** Registration interface for I2C client drivers **************/
/* Since there's no way to auto-probe the I2C devices connected to the I2C
* bus on the go7007, we have this silly little registration system that
* client drivers can use to register their I2C driver ID and their
* detect_client function (the one that's normally passed to i2c_probe).
*
* When a new go7007 device is connected, we can look up in a board info
* table by the USB or PCI vendor/product/revision ID to determine
* which I2C client module to load. The client driver module will register
* itself here, and then we can call the registered detect_client function
* to force-load a new client at the address listed in the board info table.
*
* Really the I2C subsystem should have a way to force-load I2C client
* drivers when we have a priori knowledge of what's on the bus, especially
* since the existing I2C auto-probe mechanism is so hokey, but we'll use
* our own mechanism for the time being. */
