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.

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.
