Add method to remove video driver before loading u-boot proper, when there is no bloblist passed to next stage, to avoid displaying of artifacts in the next stage, if video is not defined in that stage.
Signed-off-by: Nikhil M Jain n-jain1@ti.com --- V3 (patch introduced): - Remove video only if SPL_VIDEO_REMOVE is defined.
V2: - No change.
