With em2800 hardware, AC97 hardware can be detected even when it doesn't
exist. If, after probing for AC97, the driver won't find a companion
chip, simply prevents the load of the audio modules.

Due to hardware limitation, em2800 chips can't work at resolutions
higher than 640x576, since the URB packet size is not enough.
The effect is that the image looses packages and shows a distortion
along the vertical axes.

These variables are never used uninitialized, but the compiler couldn't
figure that out unfortunately.

The bNrInPins and baSourceID fields are common among all entities (some
of use bSourceID but this is conceptually the same). Move those two

New FX2 firmware from Hauppauge is no longer 8KB in size - it's 16KB.
This is true for HVR-1950 and HVR-1900 devices. Without this change,
new pvrusb2 users with that hardware are unable to use the driver
(because the CD shipped with the hardware only has the 16KB firmware).
