This small patch fixes a warning that I got while running coccinelle:
CHECK drivers/gpu/drm/imx/dcss/dcss-plane.c
drivers/gpu/drm/imx/dcss/dcss-plane.c:107:21-23: WARNING !A || A && B is
equivalent to !A || B
Fixes: 9021c317b770 ("drm/imx: Add initial support for DCSS on iMX8MQ")

This patchset fixes 90/270 rotations for Vivante tiled and super-tiled

DCSS supports 90/180/270 degree rotations for Vivante tiled and super-tiled

We've fixed many races in panfrost_job_timedout() but some remain.
Instead of trying to fix it again, let's simplify the logic and move
the reset bits to a separate work scheduled when one of the queue
