common: spl: spl: Remove video driver before u-boot proper
Add method to remove video driver before loading u-boot proper. When
bootstage changes from SPL to u-boot proper, this method will reset the
display controller so that it stops displaying towards the end of SPL
stage, thus avoiding displaying of artefacts when control is passed to
further stages and framebuffer region is used by some other component.
