pvrusb2: Implement sub-device specific update framework
From: Mike Isely <isely@pobox.com>
Lay down a foundation whereby it becomes possible to send customized
updates to specific sub-devices. (This becomes useful for routing
configuration, which is a very sub-device specific operation.)
Priority: normal
