Port utouch driver from TrueOS

[vi_endrift.com]

Summary

This patch adds the utouch driver from TrueOS, which supports absolutely-positioned pointing devices for use with evdev.

At the moment, the module is not automatically loaded, and devices are grabbed by the ums driver before this driver, meaning you need to detach ums before utouch can see them. I have not successfully figured out how to get the kernel to load utouch over ums for this case.

Hi,

Can this driver be merged into ums.c ?

You can use usbconfig and set a UMS quirk to prevent ums.c attach.

I would like to do that. This is merely a port of what TrueOS does, but I do believe merging them would be a better approach and I can try doing that over the next day or two.

Thanks, I'll look into that.
