Matthew Auld 141f733bb3 drm/i915/uapi: expose the avail tracking
Vulkan would like to have a rough measure of how much device memory can
in theory be allocated. Also add unallocated_cpu_visible_size to track
the visible portion, in case the device is using small BAR. Also tweak
the locking so we nice consistent values for both the mm->avail and the
visible tracking.

v2: tweak the locking slightly so we update the mm->avail and visible
tracking as one atomic operation, such that userspace doesn't get
strange values when sampling the values.
