Some devices such as the pre nv02 chips have enter and exit constraints where hardware compression must be turned off and re-enabled on resuming normal operations.
This patch extends the mode_set_base_atomic() call to pass an argument to indicate if this is an entry or an exit from an atomic kernel mode set change. Individual drm drivers can properly save and restore state accordingly.

An enum for the last arg would make this call much less mysterious. :)
