This patch fixes the following soft lockup: BUG: soft lockup - CPU#0 stuck for 23s! [weston:307] On weston idle-timeout the IP is powered down and reset asserted. On weston resume we get a massive vblank IRQ storm due to the LDI registers having lost some state. This state loss is caused by ade_crtc_atomic_begin() not calling ade_ldi_set_mode(). With this patch applied resuming from Weston idle-timeout works well.
