Require that dma-sg also uses an allocation context. This is in preparation
for adding prepare/finish memops to sync the memory between DMA and CPU.

Refactor and clean up the tw68 driver. It's now using the proper
V4L2 core frameworks.
Tested with my Techwell tw6805a and tw6816 grabber boards.

This tw68 driver has been out-of-tree for many years on gitorious:
https://gitorious.org/tw68/tw68-v2.
This copies that code to the kernel as a record of that original code.
Note that William Brack's email address in these sources is no longer
valid and I have not been able to contact him. However, all the code is
standard GPL.
