Rework entire internal controls interface to eliminate the need for
visibly defined control IDs which must otherwise be translated by the
V4L2 public interface. As part of this work, internal structures
which mimiced various V4L2 structures (video standards, audio modes)
have been reworked to actually use the native structures. This
triggered a _significant_ rework for how video standards are dealt
with (and what is in place now should be much more flexible and
forgiving for various handling less-common video standards).

When a V4L app queries a pvrusb2 control, make sure we also tell it
what the control's default value is.

Eliminate the need to track the number pvrusb2 CIDs at compile time
from within the pvrusb2 driver. This is part of a control structure
cleanup.

This change threads logic through the pvrusb2 to make it possible to
command the decoder chip to reset itself. The method is
decoder-agnostic; the part of the pvrusb2 which control's that chip's
module has to provide the final hook. This just lays the foundation.

Rename a pvrusb2 function to reflect its true meaning, and tweak the
driver initialization sequence so that the I2C adapter isn't started
until after the hardware has been given a powerup command.

Add a new audio mode V4L2_TUNER_MODE_LANG1_LANG2 (used by VIDIOC_G/S_TUNER).
This mode allows the user to select both languages of a bilingual transmission,
one language on the left, one on the right audio channel. If there is no
bilingual transmission, or it is not supported, then this mode should act like
V4L2_TUNER_MODE_STEREO.
This mode is introduced for PVR-like drivers where it is useful to be able to
record both languages of a bilingual broadcast.

Clean up a missing const declaration in the initialization pathway of
the pvrusb2 driver.

Notice and track actual hardware type of device. This information is
also used now to select the correct FX2 firmware file to load (because
they can be different, unfortunately).

The pvrusb2 driver as part of its initialization might have to load
the FX2's firmware image. We must only do this when it is actually
needed. The previous method just detected this requirement by
noticing something unusual about the USB configuration of the device.
Unfortunately with newer PVR USB2 devices this method no longer works.
What we do now is also attempt a simple non-destructive endpoint 1
transaction; failure of that transfer will indicate a need to load the
firmware.
