[Intel-gfx] [RFC] Updated Android sync patches

[Jesse Barnes]

Still have a few remaining todo items, but I'd like some feedback on these
before adding a bunch of stuff on top.

Rough todo list:
  - support for other rings
  - support for display
  - tests
  - userspace usage (I have a Mesa patch that needs a refresh, but it's
    trivial, the interesting bit will be using this in Wayland and
    X/DDX)

Thanks,
Jesse
