V4L/DVB (11204): pvrusb2: Remove old i2c layer; we use v4l2-subdev now
This change removes the old i2c module controlling layer from the
pvrusb2 driver. This is code that first had appeared in the driver
back in December 2005. It's history. Now we use v4l2-subdev. Please
note also that with this change, the driver will no longer be usable
in kernels older that 2.6.22.

V4L/DVB (11194): pvrusb2: Implement mechanism to force a full sub-device update
When a pvrusb2 driver instance first initializes, we need to be sure
to send out a complete state update for everything to all attached
modules. The old i2c layer did this by keeping a separate mask of
"stale" bits for each attached module - and setting that mask to all
stale when that module attaches. But the new sub-device adaptation
I've implemented here no longer has per-module stale bits. So instead
there's now a global "force dirty" bit that is set upon instance
initialization, before the sub-devices are attached. After the first
update, this bit is cleared, allowing for normal update-on-dirty
behavior. In this manner, we ensure that all sub-devices have been
properly synchronized at initialization.
