V4L/DVB (8900): pvrusb2: Implement cropping pass through
This builds upon the previous pvrusb2 change to more formally implement full cropping support. This enables access from the driver's V4L interface, and enables access to full capabilities from sysfs as well. Note that this is only effective when in analog mode. It also will only work when the underlying digitizer's driver (saa7115 or cx25840 depending on the hardware) also implements the appropriate functions.
