- r6xx actually uses a slightly different packet format,
although both formats seem to work ok.
- r7xx doesn't have the count multiple of 2 limitation.

The idea here is to move to a finer grained reset.
In some cases we may not need reset every block, and
in other cases we may not need to re-init the entire

radeon_fence_wait_empty_locked should not trigger GPU reset as no
place where it's call from would benefit from such thing and it
actually lead to a kernel deadlock in case the reset is triggered
from pm codepath. Instead force ring completion in place where it
makes sense or return early in others.

With the new per-crtc locking mutliple set-cursor calls could happen
in parallel. Out of sheer paranoia I've opted for an irqsave spinlock.
But if there's indeed an access from interrupt contexts to these regs
it's already broken with the old code, so this can likely just be
reduced to a normal spinlock. Otoh the pageflip completion happens
from the vblank irq handler ...
