drm/lima: set gp bus_stop bit before hard reset



[ Upstream commit 27aa58ec85f973d98d336df7b7941149308db80f ]

This is required for reliable hard resets. Otherwise, doing a hard reset
while a task is still running (such as a task which is being stopped by
the drm_sched timeout handler) may result in random mmu write timeouts
or lockups which cause the entire gpu to hang.
