[pvrusb2] PAL-Plus support

[Carsten Meier]

Hi,

first I'd like to thank you for that neat device-driver. :)
Now I have a feature-request: Is there a chance that the pvrusb2-driver
acts like a Pal-Plus-decoder? Is the hardware capable to do so? In
Germany many programs are broadcasted in PAL-Plus which provides a
true 16:9-picture at the full vertical PAL-resolution of 576 lines.

Thanks in advance,
Carsten
