[RFC] v4l2 support for thermopile devices

So want to toss a few thoughts on adding support for thermopile devices (could be used for FLIR Lepton as well) that output pixel data. These typically aren't DMA'able devices since they are low speed (partly to limiting the functionality to be in compliance with ITAR) and data is piped over
