Arrange so that the pvrusb2 driver can optionally work without a Hauppauge ROM being present - which is fairly important for devices that happen to not come from Hauppauge. The expected existence of a Hauppauge ROM is now a device attribute. The tuner type is now also a device attribute, which is consulted if there is no ROM.
