[media] pvrusb2: For querystd, start with list of hardware-supported standards
The V4L querystd implementation appears to want to narrow down the list of available standards by starting with a hardware-supported list and then attempting to detect which among those are actually available. Prior to this change in the pvrusb2 driver we started with all possible standards. With this change in place we instead narrow to just the standards that we know the hardware can actually support. For example, this removes the ATSC standards from the list if we aren't dealing with a hybrid device...
