The CRTC .disable() helper operation is deprecated for atomic drivers,
the new .atomic_disable() helper operation being preferred. Convert all
atomic drivers to .atomic_disable() to avoid cargo-cult use of
.disable() in new drivers.

The old state is useful for drivers that need to perform operations at
enable time that depend on the transition between the old and new
states.
While at it, rename the operation to .atomic_enable() to be consistent
with .atomic_disable(), as the .enable() operation is used by atomic
helpers only.

Every attempt to pin/unpin objects in memory requires
qxl_bo_reserve/unreserve calls around the pinning operation to protect
the object from concurrent access, which causes that call sequence to be
reproduced every place where pinning is needed. In some cases, that
sequence was not executed correctly, resulting in potential unprotected
pinning operations.
This commit encapsulates the reservation inside a new wrapper to make
sure it is always handled properly. In cases where reservation must be
done beforehand, for some reason, one can use the unprotected version
__qxl_bo_pin/unpin.

Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure. I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.
I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates. The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.
