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.
