msm: mdss: force revalidate layers after resolution switch 



Avoid skipping validation for all layers during ATOMIC_COMMIT
validate call after dynamic resolution switching. Though the
configs remain the same for few layers, revalidation is required
based on the new resolution as the src_split and other settings
might have changed.
