With the v4l2_i2c_new_subdev* functions now supporting loading modules
based on modaliases, replace the hardcoded module name passed to those
functions by NULL.

All corresponding I2C modules have been checked, and all of them include
a module aliases table with names corresponding to what the drivers
modified here use.

When creating a new sub-device, The V4L I2C subdev API has historically
required drivers to pass the name of the module that implements support
for the I2C device.

I2C modules can be loaded based on modaliases instead of the module
name. As the I2C device type name is already available to the
v4l2_i2c_new_subdev* functions, make the module name argument optional
and create a modalias based on the type name when no module name is
provided.

All in-tree drivers call those functions with a non-NULL module name
argument, this change is thus harmless.

This patch allows this device successfully to show video, at least from
its composite input.

I have no information about the true hardware contents of this device and so
this patch is based solely on fiddling with things until it worked. The
chip appears to be em2860, and the closest device with equivalent inputs
is the Typhoon DVD Maker. Copying the settings for that device appears
to do the trick. That's what this patch does.

The previous logic needed duplicate USB table structs, one to store
the list of the devices, and 3 sets of other structs, to store the
quirks list.

With this change, devices that require expecial quirks just need to
have a .driver_info = <quirk entry>.

It also allows adding some extra quirks, like per-model RC tables.

As a bonus, this patch reduced in 10% the data segment size:
