Subject: [PATCH] drm/vc4: Fix atomic_async_check to call the right mode_set
function
vc4_plane_atomic_async_check was always calling vc4_plane_mode_set
to validate and generate the dlist for the check. If async_check
decided it had to fall back to a sync commit, then this GEN4/5
dlist could get used on GEN6.
Call either vc4_plane_mode_set or vc6_plane_mode_set as appropriate.
Fixes: 1ab1fbbb7e76 ("drm/vc4: hvs: Support BCM2712 HVS")
