Subject: drm/ast: Don't set struct drm_crtc_state.no_vblank explicitly
Git-commit: bd2b7eb6d26e4119c157d56dbb108ca10bb6e3cc
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

As ast does not initialize vblanking, atomic helpers initialize the
value of struct drm_crtc_state.no_vblank to be true. No need to set
it from within the driver.
