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.
