V4L/DVB (6698): pvrusb2: Implement signal routing schemes
The exact routing of video and audio signals within a device is a
device-specific attribute. Hauppauge devices do it one way; other
types of device may route things differently. Unfortunately it is
rather impractical to define chip-specific routing at the device
attribute level, so instead what happens here is that "schemes" are
defined. Each chip level interface implements its part of a given
scheme and the scheme as a whole is made into a device specific
attribute controlled via a table entry in pvrusb2-devattr.c. The only
scheme defined here is for Hauppauge devices, but clearly this opens
the door for other possibilities to follow.
