V4L/DVB (11154): pvrusb2: Split i2c module handling from i2c adapter

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.
