drm/atomic-helpers: Recover full cursor plane behaviour
Cursor plane updates have historically been fully async and mutliple
updates batched together for the next vsync. And userspace relies upon
that. Since implementing a full queue of async atomic updates is a bit
of work lets just recover the cursor specific behaviour with a hint
flag and some hacks to drop the vblank wait.
v2: Fix kerneldoc, reported by Wu Fengguang.
