[Intel-gfx] RFC: drm/1915: Resource streamer initial support

[Abdiel Janulgue]

Daniel Vetter suggested at some point we need to implement getparam ioctl 
so userspace can figure out whether kernel supports RS at runtime.
For now, this will do to support the corresponding RFC mesa patches.

Based on the work of: Lukasz Anaczkowski <lukasz.anaczkowski at intel.com>
