This implements a temporary mechanism to "untrack" an i2c module from
the old i2c layer. The v4l2-subdev related code in the driver will
use this to remove a sub-device from the old i2c layer. In the end,
once the old i2c layer is removed, this will also eventually go away.

This is the first step in the effort to move the pvrusb2 driver over
to using the v4l2-subdev framework. This commit involves mainly
splitting apart pvrusb2-i2c-core - part of it is the driver's I2C
adapter driver and the rest is the old i2c module handling logic. The
i2c module handling junk is moved out to pvrusb2-i2c-track and various
header references are correspondingly updated. Yes, this patch has a
huge pile of checkpatch complaints, but I'm NOT going to fix any of
it. Why? First, I'm moving a large chunk of existing code and I'm
not going to spend time adjusting it to match someone's idea of coding
style. Second, in the end I expect all that moved code to go away by
the time the rework is done so wasting time on it now to adhere to the
standard is in the end a large waste of time.
